HUAYUAN High-end Biomass Burner--1046KW

This boiler is 349KW one.

Introduction:

The first horizontal biomass boiler in China Brand: HUAYUAN

High-end product---Longxiao series A, B, C

Technical features:

By the great effort, HUAYUAN has developed the first biomass boiler without grate. There are three kinds of hot water boilers as following:

Longxiao Series A: blue touchscreen control system, burning any biomass fuel without dark smoke.

Longxiao Series B: colorful touchscreen control system. motor frequency control system. drain the coked fuel in the combustion procession. burning all coked biomass fuel.

Longxiao Series C: large colorful touchscreen control system. intelligent control system, internet control system. drain the coked fuel in the combustion. burning all coked biomass fuel.

Characteristics:

1. Different from tradition vertical boiler, any parts of boiler could be checked and repaired. Even the fire pipes in the boiler could be replaced without boiler disassembled.

2. HUAYUAN adopts world leading patent combustion system. Boilers without grate will need no more grate transporting to solve coked fuel burning problem.

3. High temperature in the hearth could be controlled to make sure that temperature is enough high to do biomass pyrolysis gasification and complete combustion. With specially designed

airflow spraying, tar will not be attached to the hearth after longtime combustion and pipes will not be blocked by the attached tar, it will do little effect on the boiler's efficiency after long time using, this is what users will neglect. Long-time energy saving is what matters.

4. As store is directly connected to the hearth, many biomass boilers catch fire easily. Applying anti-back fire structure and back-flow prevention device, so that only biomass fuel can be put into hearth, high temperature airflow can't flow into bunker. We are equipped with safety fire protection device, even when the back-flow prevention device fails, automatic monitoring feeding system will start to force high temperature into hearth. Boiler will stop working only after cleaning all the fuels.

5. Change the traditional boiler feeding way, decrease the feeding height of bunker, increase the capacity, reduce the labor strength.

6. Traditional biomass boiler only monitor output water temperature, Longxiao series adopts touchscreen control system, clients can monitor the parameters of temperature of input water, output water, smoke, fuels in bunker, combustion in hearth etc. After the change of relevant data, it will timely remind the user of maintenance, so that to allow user to get more information about running status and energy-saving data.

7. First one to apply internet control system in biomass fuel industry, you can monitor the boiler everywhere with internet.

8. Under intelligent control, boiler will automatically operates from start-running-stop-restart. You could be an online boiler operator with high efficiency and 6 safety protection settings.

Q: Hi Folks,Could someone give me some pointers?I have a 2 year old Vokera combi boiler and recently got a leak upstairs fixed.I now notice that my hot water pressure is particularly poor both upstairs and down (the boiler is downstairs next to the tap). Also when I run the hot water tap the boiler makes a noise that I didn't really notice before.. any ideas?- I'm sure the pressure problems started upstairs (in the bathroom) and have got worse / moved downstairs, although I could be wrong!many thanks.: Check the system pressure should about 1.5 bar.If too low boiler can run noisy though this would not effect outlet pressure. Check cold water inlet tap to boiler is fully open. If you are in a very hard water area the secondary heat exchanger may be scaled up. That would reduce pressure flow from taps, bad news if so. Good luck Heating engineer for 30 years

Q: This is a gas conversion. The contractor didn't take any kind of measurement, didn't even know the rating of the old boiler so now I'm kind of screwed and pretty upset. He insists that the problem is with the house which is nonsense but I need to know my options. How much $ would I lose to return it and what is the price difference between 105k BTU output and the next size bigger?: If you hired the contractor for his expertise, he is responsible to complete the job. You may have to file a small claims court plea to alleviate the problem and be reimbursed. He should've corrected the problem if he knew what he was doing, and is a professional.

Q: The boiler comes on every minute making the sound for thirty seconds. What does this mean? What can I do to stop this?: I additionally am an engineer and have skilled this well-known hand. I hit a empty passenger automobile one time that became fouling the tracks, the driving force neglected the crossing and saddle bagged the automobile on the crossing. Thank god it became empty on the time. I doubt absolutely everyone could have been injury undesirable, however the belief nonetheless scares me. i latterly hit a guy laying alongside the tracks surpassed out below the impression of alcohol. He became exterior of the rail yet nonetheless on the binds. he's the luckiest guy i understand of. He walked removed from that one with minor cuts and bruises. Like hog-head and derail stated it keeps enjoying many times in sluggish action in my head, I consistently ask what i will have performed in any different case. Its a extraordinary feeling seeing the guy and slamming the vast handle then all you're able to do is wait, you experience such as you're helpless. it may desire to be appealing to observe on television yet in actual existence its plenty diverse.

Q: I have a boiler used only for heating my house through baseboards. My hot water tank is a separate unit. For some reason the minimum temperature on the aquastat was set to ~160 even thought the boiler hets up to ~180-200 within 20-40 minutes from being OFF (depending on the outside temp). I feel almost as if the minimum can be turned off or at least down since we don't need the water to be immediately hot.I don't mind waiting a bit longer for the house to heat up if it will save me money! I'll just set my thermostat schedule to start 30-60 minutes sooner!Let me know if I'm missing something here.Boiler - Weil Mclain WGO-3Aquastat - GeniSys Model 7505: Yes, you need at least 140 degrees for cast iron boilers. Otherwise you may have condensation in the combustion chamber or heat exchanger. This can cause corrosion problems . Since this is a fairly new boiler, you need to call Weil Mclain and get their recommendations. You could take 20 years off it's life by running it too cold. The 140 degree minimum temperature comes right from Weil-McLain's service manual for the WGO-3 series, page 21. Here is a warning from ASHRAE about the dangers of running a non-condensing type boiler at a temperature below 130 degrees. Only certain types boilers can operate safely at this lower temperature. The ASHRAE document mentions this in several places: .....A 1 million BTU/hr boiler will produce 6 gallons/hr liquid water when fully condensing ???? This water will only condense at gas temp 135?F..... Any boiler can be a condensing boiler ???? Just return water cooler than 130°F ???? Water will condense somewhere in the boiler ???? Conventional boilers will be damaged ???? By corrosion or failed refractory from condensation ???? By sooting due to blocked fins (copper fin tube) ???? Condensing boilers are special ???? They can handle flue gas condensate safely ???? They can also run at non-condensing temperatures ???? Condensing boilers need special flue material ???? AL29-4C or PVC (316L is used in Europe)

Q: The useful life of gas - fired boilers: Consider the replacement of it at that time certainly signed the contract by the contract is done in Shandong Lao Wan Boiler

Q: I have to design a boiler including the economizer, air preheater and superheater as an assignment. where can i find design equations for these? Any recommended ebooks?: See the link below. It is a boiler manufacturer's site, but I have found this 'Boiler Book' to contain a lot of good information. ASHRAE also has information regarding boiler room layouts.

Q: just want to know,TQwhen a steam boiler system for a plant having thermal deaerator, do we still need a flash vessel to separate the flash steam and return condensate?and if let say we install an economizer, the feedwater after the economizer will be pumped into boiler water tube by the feedwater pump, even though its temperature is around 150'C, it will not become steam because of the pressure, but when it reaches the water tube of the steam boiler, will it become steam?because the water tube have one sensor where it will detect the water level inside the tube,if steam formed and water level low, the boiler will have problems?help help helpTQ: Deaerator and flash vessel have totally different functions.. the deaerator removes NCGs (O2 particularly) in the feedwater while the flash vessel recovers steam from high pressure blowdown or condensates. Normally the economizer is integral to the boiler and feedwater from the feedwater pump goes to the economizer tubes and then to the to the boiler drum. Depending on the size and capacity of the economizer, the water entering the boiler drum is ideally near saturated. The near saturated water goes down the downcomer tubes where it picks up heat from the flue gas (then to the water drum or mud drum if your boiler is of bi-drum type, or to the water headers if your boiler is of single drum type) and goes up through the riser tubes and then to the steam drum again. In the riser tubes, the fluid is a mixture of steam and water. The steam is separated from the water in the steam drum. There is no sensor in the boiler tubes. The drum water level is measured using a level lauge, switch and/or transmitter. The choice of level instuments type depends upon the sophistication of your boiler. The quantity is usually according to applicable codes (i.e. ASME Sec 1). The drum level output manipulates the feedwater control valve and regulates the flow of the feedwater. To avoid problems caused by low water level in the drum, a low water level cut-off is usually provided which shuts down the burner/combustion system when this cut-off is reached.

Q: Accesses air % in boiler?: Power plant boilers normally run about 10 to 20 percent excess air. Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. Gas turbines runs very lean with up to 300 percent excess air. But actually it depends on the fuel consumption rate and the output rate of the boiler and is controlled precisely by damper.

Q: how does a marine boiler plant work?: I answered a question similiar to this last week. Search for the question Can you give me an idea of how does a ship moves?. A marine boiler plant works alot like power station boiler plant. It super heats treated water with fire or nuclear fission to create dry steam. the steam is forced through a turbine, or series of turbines(high pressure and low pressure), creating work, which can be applied to propulsion or electic generation. As for the boiler itself, there are many designs, but basically it is a furnace with many tubes in which the feed water circulates to be heated. The steam is collected inthe steam drum, travels throug the dry pipe, past stop valves, through a series of heaters, dryers, and air ejecters, until it reaches the high pressure turbine, then it is heated and dried again, is forced through the low pressure turbine. The steam is then condensed into feed water, and pumped to another heater ,and then pumped back to the boiler. I am a deck officer, so it's been a while since I studied the steam cycle, but that is the very basics.

Q: I work security at a lumber mill we normally don't go in the boiler building but we check the boiler valves across the property on our patrols. I'm just curious how a boiler works and what one is or what it's purpose is?: A boiler is basically a giant kettle. Water is heated by burning something, perhaps gas, perhaps oil, perhaps waste timber as it's on site, to produce hot water and steam. This is doubtless used in various timber related processes, such as making particle board, plywood and so on, and may well also heat the buildings.
