threaded flue pipe steam boiler 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.
threaded flue pipe coal fired hot water boiler | Industrial ... Chapter 10: Boilers and Pressure Vessels, California … For heating or hot-water-supply boiler applications, the boiler room shall be equipped with a floor drain or other approved means for disposing of the accumulation of liquid wastes incident to cleaning, recharging, and ...
as standard coal fired threaded flue pipe chain grate steam boiler find reliable . With more than 30 years of manufacturing boilers, the company has formed more than 400 varieties of gas boilers, biomass boilers, coal-fired boilers, heat-conducting oil boilers, etc.
A Category I vent system works by allowing heated flue products to rise vertically, so the vent pipe must rise vertically from the boiler vent connection as soon as possible. You should also limit the length of the horizontal flue pipe. All horizontal runs of vent pipe must rise 1/4 inch per foot of run to maintain proper draft in the vent.
All accessories for boilers be sure to make sure you check that the item is compatible with your specific boiler. The flue pipe is an pipe that takes out the carbon monoxide and other horrible gasses outside of your property. you can have vertical flues or horizontal terminating flues.
According to the latest gas boiler flue regulations, the pipe should be continuous and have all the joints assembled safely and correctly. Keep in mind that gases expelled from traditional units differ from those expelled from high efficiency ones. So, the flue type differs as well. Most modern models feature two pipes. One is fitted inside the ...
