1. The use of circular tube plate and threaded pipe composed of the drum, the drum made of quasi-steel quasi-elastic structure, the removal of the tube plate area of the pull, reducing the  boiler  stress. Tube plate within the plate back from the two back to solve the problem of tube plate crack.

2. Boiler feed water using the spray device, so that the number of water into the decline of several times, thereby greatly improving the speed of the riser to ensure the safety of water cycle to solve the single pot pot of water and fire tube boiler water supply reasons.

3. The furnace body is arranged on both sides of the convection tube and is heated by the convection tube bundle so that the intake air temperature of the exhaust pipe is greatly reduced (not less than 700 degrees). O Front tube sheet prevents cracks.

4. Efficient heat transfer screw pipe use, get enhanced heat transfer effect, to achieve the boiler heating, improve the characteristics of fast, improve the boiler thermal efficiency.

5. Compact structure, compared with the same type of boiler, small size, saving boiler room infrastructure investment.

6. Stable operation, adjust the intensity, there is sufficient 110% overload capacity.




    Fired  coal biomass hot water heater industrial use boileris small in size, big in output power, rapid in

pressure rise and higher in heat efficiency. This is the first domestic production. The boiler is a national

mechanical and electrical energy saving product with national patent the arched tube plate and the thread

smoke tube boiler drum, The drum  is  composed  of steel into a quasi  quasi  elastic structure, canceled

braces tube plate area, reduce the stress in steel tube plate. By two return to return, to solve the problem

of tube plate crack. Independent adjustable wind chamber under the fire grate, and wind comes from two

sides. Ventilated section ratio reaches 100% , and can be adjusted flexibly and air flows evenly.

Anthracite class II ,biomass fuel




1. Biomass pellets fuel calorific value, calorific value of 3900~4800 kcal /kg or so,

    after carbonization of heatup to 7000 - 8 million card /kg.

2. Biomass fuel particles of high purity, without other heat generating debris,

    the carbon content of 75 - 85% 3 - 6% ash, water content of 1 - 3%,

    absolutely  free of coal gangue, stone and other  impurities without

    heating instead of heat consumption, it will directly reduce costs for enterprises.

3.The biomass pellet fuel does not contain parathion, so it does not corrode the boiler

    heating instead of heat consumption, it will directly reduce costs for enterprises.
