boiler for heating the rolls 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.
One of the problems in manufacturing a boiler is in rolling the plate for the shell. Boilermakers’ rolls, as shown in Figures 3.2.7 and 3.2.8, cannot curve the ends of the plate and will, hence, leave a flat: Roll A is adjusted downwards to reduce radius of the curvature. Rolls B and C are motorised to pull the plate through the rolls.

By using
Wet underfloor heating systems can warm a large area more efficiently than traditional heating systems or electric underfloor systems. An advantage of underfloor heating systems is the way it warms the initial area by conducting the heat through the floor surface versus using a forced-air heating system.
2006-3-29 · I think perhaps you are not asking the right question - the most efficient boiler that you can buy is an electric boiler which operates at about 99.5% efficiency or a combined heat and power unit. The stated efficiency of a boiler is only part of the equation - why are you asking the question.

2001-9-6 · The calculations for the figures in Table 1 assume that only 10 boiler horsepower (bhp) is needed for process heating and the central boiler has a nominal 150 bhp rating. This is the energy output of the boiler at rated capacity, and one bhp is equivalent to 34.5 pounds of steam per hour or 33,446 Btu/hour (mean) at 212 ° F and higher.
