1.Structure introduction :
This product is a double drum ( S ) vertical ( Z ) room combustion ( S ) fuel ( Y ) [ or gas ( Q ) ] boiler.
a.The boiler is a natural circulation double longitudinal drum ' D ' boiler. The left side is the furnace, and the right side is the convection tube bundle. The boiler adopts micro positive pressure combustion. The burner is arranged on the front wall, and the convection tube bundle is arranged on the right side of the furnace. The flue gas generated after the fuel is fully burned in the furnace is transversely scoured from the rear outlet of the furnace to make the convection tube bundle fully endothermic. Then it enters the economizer from the rear of the boiler to make the economizer further endothermic and finally discharged into the chimney.
b.The upper and lower double drums are connected by welding, and the upper drum is supported on the lower drum by convection tube bundle. The lower drum is supported on the base by two supports respectively. The front support is movable and the rear support is fixed. The weight of the whole boiler body is concentrated on the support and then transmitted to the ground. In order to obtain good conditions in the pot, there are internal devices such as water supply pipe, overflow tank, underwater orifice plate and uniform orifice plate, as well as continuous sewage discharge.
c.The cross section of the furnace is ' D 'shaped, and the water wall of the furnace is composed of a dense row of tubes and a finned tube at the rear of the furnace to form a radiant heating surface. There are fire holes in the middle of the rear wall, and test holes are arranged below it, generally for the test temperature. There is a well-structured explosion-proof device at the upper left rear to ensure the safe operation of the boiler. The front wall is not arranged on the heating surface.
d. Between the upper and lower drums, dense tubes are arranged to form the convective heating surface. The high temperature flue gas scours the convection tube bundle horizontally forward, so that the convection tube bundle absorbs heat fully.
e. In order to reduce the exhaust gas temperature and improve the efficiency of the boiler, the casting economizer is arranged in the tail.
f.because the boiler is positive pressure combustion, so the use of fully sealed furnace wall. The inner layer of the furnace wall is made of aluminum silicate fiber brick and lightweight refractory brick, followed by aluminum silicate fiber felt, and the outermost layer is all sealed and welded with steel plate as the outer panel.
g.the use of imported automatic burner, can also be selected according to user requirements of domestic burner.
2.Product characteristics
a. The boiler is micro-positive pressure combustion, the water wall of the furnace with close-packed tubes, good sealing performance, small air leakage coefficient, enhanced combustion and heat transfer, high thermal efficiency, compact size, simple adjustment operating system. The sealing guard plate has a beautiful appearance and the boiler room environment is clean.
b. boiler installation is simple. The boiler is assembled in the manufacturing plant with high assembly degree and strict quality control. After being transported to the site, the economizer, platform escalator, boiler pipeline and auxiliary machine can be put into use.
c.The boiler matching burner has reliable ignition program control, flameout protection and interlock protection device. The boiler has a high degree of automation and can ensure the safe operation of the boiler.
d. It is convenient to start and stop the boiler. The boiler combustion system, steam-water system and flue gas system are simple and reliable. The operation is flexible. The heat capacity of the furnace wall is small.
e. The soot and harmful gases emitted by the boiler are lower than the emission standards of China 's boiler soot, reaching or higher than the national environmental standards, suitable for use in any regional environment.
- Q: what are the heat transfer mode in a boiler system?
- boilers can b fire tubes or water tubes...just search for them..in google..you ll get for sure..
- Q: Where can I find it?There are no stickers on it... I know it's old, but I would think the model number would be engraved somewhere??
- There should be a tag on one of the panels if not google the approx year of your boiler and you may find a model. If no luck, you will have to take off the stove pipe and top cover. Here you should find a brass tag with a number on it (BTU rating) towards the front (burner side) and if still no luck count the sections of the boiler. These are approx 3 inch Vertical boiler sections with a front and back part. Here you can maybe call a plumbing supply and they can look it up. Im just curious, why do you need the model number? Most people don't ask unless you have an issue with the boiler
- Q: Hi - i don't know if anybody can help me... i am having a nightmare trying to repressurise my boiler. A Vokera Syntesi 25e. My filling valve is permanently connected so i did as my boiler instructions said to increase the boiler pressure and turned the filling loop to the vertically down position. I expected to hear water entering the boiler and the pressure to rise but nothing happened. My central heatign system is working fine - all radiators and warm water nice and hot - so I dont know what the problem can be. My pressure is below 1 bar at the moment so would like to increase it. The filling valve loop reaches from the filling valve (the one with the three normal/off/filling loop positions) along the loop to another tap on the left which has a black knob marked with open/shut in two directions. What is this and am i supposed to do anything with that? Any help would be much appreciated
- Could be that the filler loop is connected to the stored water and not the mains. If that is the case then a pressure of more than half a bar is unlikely. Things should be O K as long as the pressure remains about this setting. Is the filler loop the type that has two taps on it?
- Q: there's alot of detail in the new molds i have which require different colors, does the dbl boiler method keep the candy melty longer? and wut should the consistency b when painting in 'features of the face' ?
- Double boiler definitely. Once the candy melts, the water keeps it melted. However if the water gets too hot, the candy can clump, if that happens put a tiny amount of shortening and stir. Once the candy melts, turn off the heat and just use the chocolate like that. The consistency should be liquidy, for molds, you can use a paintbrush, or lollipop sticks to paint the features. Freeze them first, then add the remainder of the chocolate. I made candy in molds every holiday, sometimes up to 4 different double boilers with 4 different colors. I find that the double boiler is your best best. It takes a while though, the water should be tepid, but if its too hot, the chocolate will harden again. Good luck.
- Q: i have a Baxi boiler and also the air pressure goes down dramaticly when i bleed the radiators. so if you could also tell me how to get the pressure back up that would be great :D
- the heating works on pressurised system when you take air out via bleeding a rad the pressure needs to be topped up again.look under the boiler and you will see a silver braided pipe in a half loop, on the end of this is a valve like a washing machine tap turn this a quarter turn and watch the temperature gauge go up when it gets to 1.5 bar turn it off. Always keep an eye on the pressure valve as soon as it drops to zero you will have no hot water or heating.
- Q: If a bath is filling upstairs, taps down stairs cannot be used at the same time?
- Yes you are right. A combi is a one tap boiler, but you can put as many taps as you like on the circuit, but you will only get a full flow from one at a time. If somebody runs the bath, you have to wait before you fill the sink. But they are only suitable for small places and this is not really a problem, you just have to learn to live with it. The only real problem with them is if you are running a shower and somebody else turns a tap on downstairs, the shower stops running just as you are going to wash the soap from your eyes. No fun that. But all systems have this same problem to a greater or lesser degree. So go ahead and get a combi, as long as you understand they have limitations , they are very good.
- Q: The workflow is as follows
- And then down the pipe down to the water wall into the collection box, the formation of soft water mixture rose back to the drum, through the soft drinks separator
- Q: Ive had a few
- It was probably named a boilermaker because it was popular with blue-collar folks like iron workers...just a guess, I don't really know.
- Q: My boiler furnace is almost 55yrs old. Today I had it inspected and was told it is now unsafe and it would be $1000 to repair but advised to replace as the repair may only hold it another year. Told an 80% efficient one would be $6000 and 90% would be $9000. This is for a standard ranch home approx 1300 square feet with full basement.Any hints from pro welcome.
- I have a 40 year old boiler and was given about the same figures ballpark, not in writing. I live in No VA area for a price comparison. Lucky for me the pump (to the baseboard heat) was stuck and repairable, however that was the recommendation I received as well.
- Q: When looking at the cost of heat and energy bills, is a boiler hot water heat costly for your bill during the winter months than forced air
- A boiler is just a method of heating as opposed to a furnace. A boiler uses electric,gas or oil just like a furnace, but is heating water, and then the water is used to heat your house. This is more efficient that just heating the air
