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 is the difference between a boiler and water heater?? are they the same?
- Boiler is made to put out steam hot water is for heating Water
- Q:what is the Boiler Furnace?
- With a furnace or warm air system, air is used to conduct heat from the furnace to rooms in the house. Air is warmed as it passes over a heat exchanger, and then blown throughout the house by a motorized blower. Sheet metal ducts channel the heated air to various areas of the house, and the heat enters each room through registers. Boilers, or hydronic heating systems, use heated water to supply heat to the rooms in the house. Boilers send steam through pipes to steam radiators or hot water through baseboard radiators, radiant floor systems, snowmelt systems or pool heaters.
- Q:I think every women I dated either was totally dispassionate OR a complete bunny boiler. Why no in-between?
- You're obsessed with the bunny boiler thing and that movie, aren't you? That is pretty creepy! I don't know why you had no in-between, as most people would fall in that range. I think you just have rotten luck, unless you were, for whatever reasons, setting your sights on these types, or vice versa. Either one, but especially the bunny boiler - would be a complete turn-off!
- Q:We are thinking of getting a new boiler fitted and was just wondering how much other people paid basically so I dont get ripped off.Am having a quote tomorrow We will need everything replacing i think.
- fifteen hundred to two thousand dolars this was a few years back prices might of gone up since then.but i am sure not that much waite for your quote.good luck.
- Q:how much is a gas boiler for a single family home with installation??
- The average cost for just the boiler runs anywhere from $1,799 up to several thousand. A new boiler replacement with labor can cost between $4,000 to about $8,000+. It just depends on which boiler you are looking for and how efficient you want the boiler to run. Remember, you get what you pay for--money spent now on a great system can save greatly on your bills over the next 10-20 years.
- Q:My problem is how to start handling this problem. Do i need to consider residue as a flue? Dear engineers out there, really needs your help! Thanks!
- You will need to determine the steam pressure to be generated and from that you will know the steam saturation temperature. You will need to know if the stream will also be superheated. The availability of the fuel will determine the steam generation rate. You will need the heating value of those residues ( or of the various residues) and the available, sustained feed rate of the residues to determine the heat rate available to the boiler processes. Based on the chemical composition of the residue you will need to calculate the combustion air flow rate and add about 20%. Some of the available combustion heat will be lost through the boiler insulation. Considerable heat will be exit through the hot exhaust stack and some will be lost in the discharged ash. Some of the heat in the hot exhaust gasses can be used to preheat the combustion air and some to preheat the boiler feed water. The exhaust gasses must not drop below around 350F to prevent condensation of corrosive acids coming from sulfur compounds in the fuel so the amount of exhaust heat recovery is limited. Then the balance will be available to heat the steam. Associated with the generation of steam will be the power required for boiler feed water pumps and the induced draft and any forced draft fans. These may be either electrically or steam turbine driven. There will be an auxiliary condensate return system and a boiler make-up feed water supply and treatment system. There will be electric drivers for the conveying , preparation and injection of the fuel supply and for ash removal.
- Q:I just removed an old oil burner and replaced it with a natural gas boiler. For cost reasons I am also installing a natural gas water heater. Both are atmospheric vented. Can I put the 2 exhaust pipes together in a Y and vent up through the chimney using the old oil burner piping?
- A natural Gas Boiler has to have its own exhaust pipe seperate. If you join another appliance into the same flue, it can impede the exhaust gasses from the boiler escaping efficiently. When this happens the boiler will shut down automatically.
- Q:We are looking to replace our existing Worcester combi boiler (about 10 years old) with a newer condenser model. Two of the quotes that we received mentioned that the diameter of our gas pipework may not be sufficient.So my question is: is this correct? Our flat is fairly small (5 radiators) and the existing combi boiler works fine with this pipework, leading me to think that this may be a bit of a con. It wasn't mentioned by any of the other plumbers who quoted us, either.It would be a royal pain to change the pipework, as it is a listed building, and the pipework itself can be no more than 12 years old, as this was when the building was converted to residential dwellings.Thanks,JP
- It is seen as good practice to have a combination on a 22mm gas pipe. This is not always necessary but I would recommend it as it can effect boiler performance. British gas used to refuse to take people on to a contract that had 15mm gas supply. Obviously the smaller the input of the boiler the more chance that 15mm will be fine, check the manufacturers instructions for the boile, (avail on line and see what they say)
- Q:does anyone know how much a bryant bw9 boiler costs w/install?
- The boiler would be between $3,500.00 - $4000.00, usually 8 hrs labor - $500 - $700.00 plus what ever materials are needed say $500.00 - $1000.00 so a total of $4700.00 - $5700.00
- Q:What is the effect of the main steam pressure on the steam turbine?
- If the various parameters are equal to the rated value during operation, this condition is called rated operating conditions.
