Product Description

   7MW /Industrial energy conservation wood fired biomass hot water boiler

     7MW /Industrial energy conservation wood fired biomass hot water boiler has a

compact structure,The furnace wall light ,  light weight beautiful appearance, high

strength,grate thick,long  life and other advantages. Long steaming cycle, complete

specifications, can achieve different thermal environment,Is an advantage such as

steam boiler safe and reliable operation, better steam boilers,energy saving, enviro-

nmental protection, low water quality requirements, air distribution  characteristics  

of reasonable, flexible adjustment Can be adjusted according to the actual situation

Combustion conditions,mechanical operation,low laborIntensity, reasonable structure,

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

occupational services.









  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.
