Introduction:

China's first disc cyclone biomass boiler Brand: HUINENG ZHIZUN

Applied fuel: Biomass and wood pellets (including few coking pellets)

Technical description:

1. Base on the 2012 patent cyclone combustion technology, we develop disc cyclone further combustion technology, which increase the temperature in the hearth to accelerate the process of pyrolysis gasification and makes more complete combustion. The heat transferring system prevent the tar attachment and tube block.The heat efficiency of boiler won't decrease after long-time use.

2. Natural anti-back fire design for feeding system

3. Variable frequency speed control system makes feeding system more stable.

4. The adoption of high-efficiency energy-saving tube makes heat efficiency of our boiler exceed national requirement.

5. Full-time cyclone technology prolongs the maintenance cycle.

6. Monitor system for bunkers, it will warn clients when there is no fuels. One-button control system makes automatic running and safe operation

7. Bevel design of bunkers reduces the feeding height greatly, makes fuel feeding easily, also enlarge the capacity.

8. Zincification-and-galvanize for appearance makes boiler exquisite and durable.

9. Internal equipped with dust catcher technology, which makes more environmental-protection emission, less than natural gas emission.

Q: I have science homework and I'm really stuck please help ?!?!?!: A gas boiler is supposed to produce heat which it does with 100% efficiency but not all the heat is used for what it's intended for, some of the heat goes up the flue with the exhaust.

Q: I mean it's pretty freakin' awesome. Or do you guys prefer Wall Street or Trading Places?: Actually, it's probably the worst movie relating to the stock market, as it's entirely unbelievable. Wall Street was fine, but a bit over the top. Hollywood has a hard time grasping even simple economic concepts.

Q: along with the blue light, which is flashing intermittently ..ive tried re-setting it with no luck...anyone know what I should do? My plumbers a bit stuck too!: do what everybody does with their appliances that malfunctions 1. if the soft boot doesnt work (reset button) 2 do a hard boot, meaning. turn the whole thing off, remove all electric or gas power. In short, shut it down. Then turn on power and its internal reset MIGHT work. 3. Call the manufacturer, who will also tell you the same thing anyway but this is done just in case they have some last measure before you ask for your money back 4. Do a real boot. Kick the %$#@ .

Q: The pressure guage is reading 3 bar and water is continuously running from the roof overflow pipe.What should I do to reduce the pressure immediately and what is the problem likely to be .Unit is 1 year old: If the boiler has been loosing pressure regularly and you have been topping it up with the filling loop you might have left it open slightly.If this is the case then you either have a leak or as already stated the expansion vessel has no air charge in it and it needs pumped up. If you have not been topping up the pressure then the filling loop might be faulty or the plate heat exchanger has a split in the weld and is allowing mains water in to the boiler/heating system. If the boiler is only one year old then i would phone the installer to come back and check it over.The boiler will have a guarantee which may or may not still be valid but is still worth checking out.

Q: what is the use of circulation pump in boilers?: A boiler circulating pump is often used to pump water from the boiler through a heat exchanger - for instance an exhaust gas economiser located in a ship's exhaust uptake or a heat exchanger in a nuclear power plant. The allows the boiler to be used as a steam / water drum while the heat necessary to produce steam is provided by an external source. In some cases circulating pumps might be used especially in a tank type boiler, e.g., a Lancashire or Scotch boiler to prevent dead spots in the boiler where there is little or no movement of the water a consequent cold or hot spot. It helps keep the temperature constant throughout the boiler keeps the water moving around the heat transfer surfaces. If an isolated part of the boiler becomes overheated it can weaken it there is a possibility of failure. If part of the boiler is colder than the rest of it, it can cause mechanical stress of the boiler structure.

Q: hi,would i be correct in assuming that all limiting factors remaining constant, an increase in boiler steam pressure will also increase output to turbine and of power generated? also, if so, will increasing pressure through using more coal (thru quantity/quality) also necessitate high amount of expenditure on refurbishing the systems?thankssameer: You are correct in the first part - increasing boiler pressure will increase turbine output as the higher pressure steam will contain more heat energy. As for the second part, I will say a cautious yes. Increasing the coal quantity will increase demand and wear on conveyors transporting the coal, increased wear on the milling plant grinding the coal (assuming modern pulverised fuel plant) and increased demand on the fans both supplying combustion air and removing flue gases. I do not see a great change in wear on these fans so I do not think there will be an increased maintenance need. There will also be a greater demand and wear on the ash and dust disposal plant with resultant increased maintenance requirement. As far as changing the quality of the coal is concerned, if the new coal has a higher calorific value but the same hardness and ash content, there will be a higher heat output to the steam but no extra demand on milling plant and ash disposal plant. However, if the hardness of the coal rises, there will be increased wear and increased maintenance. Sorry if the last part is a qualified answer but it really depends on how the coal changes - calorific value, hardness, ash content etc....

Q: Why does a gas boiler switch off when the water pressure is too low? What are the consequences of relighting the pilot when pressure is below normal?: Would suggest that your system has lost pressure.

Q: 1025t / h boiler what it means: Note: meet the requirements is that the design of the boiler, and the boiler in the chromium marked on the rated steam parameters, the general capacity of the boiler there are steam pressure, steam temperature, furnace feed water temperature.

Q: An iron boiler of mass 150 kg contains 590 kg of water at 12 degrees Celcius. A heater supplies energy at the rate of 9.7×104 kJ/h.a) How long does it take for the water to reach the boiling point?b) How long does it take for the water to all have changed to steam (including the time to reach the boiling point)?: In the UK washing machines often have both hot and cold feeds- thats for our USA cousins. You are right in thinking that the machine will heat the water if that coming in is not hot enough. However, if you only have cold feed available you must use a T or Y junction and feed both machine inlets with cold water. For some programmes the machine will open the hot feed only as it is going to do a hot wash and then adjust the water temperature if not hot enough- if no connection it will not fill. For cooler washes it will open the cold feed only and heat the water as there is a good chance your hot feed is too warm. The junctions are available at all DIY outlets. The heating is done by a mini immersion heater fitted below the drum.

Q: Please help me out with the detail regarding minuimum percentage of NDT to be done in construction of high pressure boilers with reference to relevant codes Standards (ASME).: The amount of non-destructive testing depends upon the design safety factor used for the boiler, which in turn determines the plate thicknesses used to fabricate it. The design safety factor is determined by the types of welds used and the amount of radiographic inspection performed on the welds. These are all as specified in the code. After completion of fabrication of the boiler and of all radiographic inspection, the boiler must then be hydrostatically pressure tested to 1 1/12 times the design pressure. Spot radiography of all the welded seams is usually performed as a minimum, but in many cases the shell will be 100% radiographed to save on material and fabrication costs. An increase in the amount of radiographic inspection allows them to use thinner plate materials.
