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:This is a 2 part question. Thanks so much in advance. Does the boiler control all the hot water in the home? Meaning the baseboard heater AND the tap water? and why does it take so long for the hot water to come up to the shower? It takes about a good 5 minutes! Thank YOU!
Answer 1 is NO. they are 2 separate systems. The boiler gets its water from the same source, but it is in a closed system, never mixing with tap water. Second answer: the only thing that would explain that long a delay is distance from the hot water tank coupled with low pressure due to clogged pipes. The clog here is rust and scale on the insides of old galvanized steel pipe. I've removed pipe that had so much clog that light could not be seen from one end to the other. Only solution is to repipe, using copper.
Q:I live in Scotland. I know it's summer but I am still cold. My heating is not working. I want to have a bath and there is no hot water. My boiler is pretty new and was working fine yesterday. What is the deal?
Check the fuse/breaker. Is it on a timer? If it is gas, is the pilot lit or is it self igniting?
Q:i recently installed a Kerr wood boiler in my house. I used it for 40 days to date. My last electric bill came and the bill was 40 dollars higher than the previous months. was wonderin if wood boilers use much electricity?
Depends, does electricity exist? If so, we'd probably use high compression steam or other gas to power many things. However, the Internet, tv, and fm Radio would not exist. Surprisingly, am and shortwave radio would work, if radioactive diodes were used. If electriciy simply didn't exist, life would be totally changed. Life would not exist. Everything would be A mass of random protons and neutrons, the universe would look pike a giant could, however, light and such wouldn't exist either, so nothing would be visiable. In short, we'd have universe soup.
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:My boiler Vaillant Eco tech plus 824r1 is not turning instead it says F61, can you give me any suggestions on why it is doing this?
Looks like an error code. Find your owners manual and read it, or call a boiler tech. You do not want to jack around with this if you don't know what your doing. It could give you CO poisoning and you'd wake up dead. BTW, took me about 5 seconds to learn that F61 means you have a bad gas valve. You really do not want to tough this! Astrobuf
Q:Our boiler in the building keeps flicking on and off and on and off and the pipes keep making these loud cracking sounds. Anyone know what causes that? (already waiting to here back from the landlord)
The boiler probably has either too much, or not enough water in it. Look at it and see if there is a glass tube that shows water level. There should be a mark on it to show you where the level should be.
Q:What is the role of the boiler energy efficiency
Industrial fuel, gas, coal-fired boiler use efficiency of about 70%, in a waste of heat, the majority of flue gas heat.
Q:We moved into this property at the end of July and could not find a Gas Safety Cert so asked the letting agent about it who got onto the landlady only to find that there wasn't one. had 3 gas engineers since all saying that the boiler is at risk as the working pressure is to low from that at the meter and that I can't use it so have had no hot water or heating for 3 weeks now.What are my options?
Presumably when you rented the property it was stated as having heating and hot water which now it hasn't. Concerning gas safety I would think that for rented properties that would be illegal (but please check) If it is illegal threaten to pursue the matter further. If not you should at least negotiate a lower rent to cover your extra electric whilst the matter is looked into. Also ask about electric safety certificate and fire alarms. if that doesn't work tell the agents you are having it investigated yourself because you think you may get CO poisoned. (which if no gas safety cert might be true)
Q:I just had a new system put in 2 years ago. The heat worked last week, all of sudden, the circulator is making a humming/buzzing noise and my heat is not working. I follow the pipes and the water comes in cold, goes through the boiler, the pipe is then HOT, but then it connects to the pump, and the circulator and by that time, the pipes are cold. The circulator is also making a humming/buzzing noise. I've tried to reset the circuit breaker, but that hasn't fixed the problem. Please help...its getting cold up here in the northeast!
Gizmo is right again! I would try a rap with rubber hammer while the pump is energized. Sometimes this will free the pump. But, you should probably get a new one , just in case. Find out why it failed. Is it sized right, is the feed valve working? Call a trusted plumber and have him look for an hour! Good luck!................
Q:What is the boiler cold state debugging and hot debugging?
Boiler cold commissioning: boiler body pressure test, the pressure gauge, safety valve calibration, all the boiler auxiliary commissioning operation.
