strong power,It has the following advantages:high degree of automation,high thermal
efficiency, equipped with dust removal equipment to reduce environmental pollution.
verticalCoal-fired energy-saving steam boilerDZL4t,DZL8t,DZL10t, widely used in
hospitals, universities, hotels, supermarkets, garment factories paper mills, food
processing plants and so on. Industrial and mining enterprises, organs, schools and
7MW /Industrial energy conservation wood fired biomass hot water boiler is small in
size big in output power rapid in pres-sure rise and higher in heat efficiency This is the
first domestic production.natural circulation boiler is a national mechanical and electrical
energy saving product with national patent High heat steam boiler. The arched tube
plate and the thread smoke tube boiler drum, the drum is composed of steel into a 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 Natural Circulation Coal
Fired High Heat Steam Boiler Independent adjustment wind chamber under the fire grate
and wind comes from sides 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 heat up 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,
and can prolong the service life of the boiler, and the enterprise will benefit greatly.
