total heating surface area of boiler - Bing is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
The earliest such measure of boiler output, the “nominal or rated boiler horsepower,” was simply based on the area of the boiler's heating surface. Each 10 square feet of surface represented 1 boiler horsepower, so a boiler with 100 square feet of heating surface would be rated at 10 boiler horsepower. Because boilers vary greatly in design
26/2/2012· I am currently working on designing of a fire tube boiler. I have to calculate the heating surface area. I've heard a rule of thumb that 1 sq ft of area is required to produce 7 lbs of steam.
Boiler Surface Area: More is not Necessarily Better. The example also shows that you can have comparable performance even when the the total surface area varies by 9% (for each boiler, total area = sum of furnace, evaporator, economizer areas, which total 13,158 vs. 14,336 sq. ft)
The cost to install a central heating boiler varies greatly depending on how big an area you have to heat and how cold it gets in the winters where you live. For a 2000 sqare foot home, it appears that it would cost between 6 and 8,000 dollars to purchase a boiler and have it installed.
