dzl horizontal coal and biomass fired steam boiler
Product thermal capacity : 1-20 t/h Working pressure : 0.7-2 Mpa Available fuel : Nature gas, coke oven gas, biogas, methanol, liquid propane gas, diesel, heavy oil, light oil, crude oil, etc. Available industries : Heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, hospital etc. Introduction:
dzl horizontal coal and biomass fired 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.
DZL series coal fired steam boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate.DZL series coal fired steam boiler uses the new scientific achievement, such as arch tube plate, screw fire tube to solve the problem of tube plate flaw, water wall tube explosion, low efficiency, insufficient output, poor adaptability of coal, improve the heat transfer.
Alibaba.com offers 3,322 dzl horizontal coal and biomass fired steam boiler products. About 97% of these are boilers. A wide variety of dzl horizontal coal and biomass fired steam boiler options are available to you, such as industrial, power station.
8 tph DZL biomass-fired steam boiler for textile factory. Hangzhou Yunsen Textile Dyeing and Finishing Co., Ltd. was founded in 1999 and is part of the Zhejiang Yunsen Group. It processes color yarns, singein...
Coal boiler (also called coal fired boiler) is widely used to generate thermal energy by burning pulverized coal that is blown into the firebox. Coal can provide lower operating costs in comparison to other fossil fuels like oil or natural gas, it is one of the cleanest fossil fuels available today due to the state of the art computerized ...
DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace.
First,you know DZL Coal Fired Steam Boiler is a new eco-friendly and energy saving product co-developed by our company and Professor Li Zhiguang a famous boiler expert, professor of Harbin Institute of Technology and director of Beijing Institute of Light Boiler. It is called as a revolution of industrial boilers by domestic and foreign experts.
DZL Chain Grate Coal Fired Steam Boilers adopt chain grate or travelling grate fuel feeding design. It adopt horizontal three pass water tube and fire tube structure. DZL chain grate coal fired boiler realize automatic fuel feeding and slag removing process, which save a lot of labor work. Feature of DZL Chain Grate Coal Fired Steam Boilers
Coal fired boiler generates thermal energy by burning powdered coal, biomass boiler is very similar to coal boiler by burning logs, pellets or chips. These two boiler are widely used in power station, chemicals, textile and printing and dyeing, energy, mining, paper making, agriculture industries, etc.
