Product introduction

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. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection. 


Product Advantage:

1. The design of biomass boiler silo and feeding device is an important part to ensure the biomass boiler safe and reliable operation, it also has the advantages of flame Isolation and fuel tempering precaution.
2.Since biomass fuels has the characteristics of low carbon content, high volatile,low sulfur content and ash content, low density,.
3.Thanks to adequate heating surface, the combustion heat can be fully absorbed by heating surface and transfer to working medium, improve the fuel burn rate and the thermal efficiency of the boiler.
4.High content of alkali metals in biomass fuels allows low ash melting point,which leads to deposition , slagging and corrosion.
5.Can be applied in thermal power plant, heating company, food & beverage, cement plant, paper mill, chemical industry, pharmaceuticals industry, textile industry, coal industry, steel & iron industry, mining industry.
6.DZL packaged boiler can burn both coal and biomass fuel with a high efficiency.
