Product Introduction
Haiqi Biomass Sawdust Combustion Technology is from Sweden. Its principle is similar to circulating fluidized bed. It uses semi-vaporized suspension fluidized combustion of biomass dust through radiant heat and convective heat, and high-speed cracking, its thermal efficiency is as high as 95%. The biomass sawdust fuel is completely burned in the furnace by three-stage vortex aeration, and the flame is blown out to the energy-using equipment by the high-speed combustion instantaneous explosion. Save 60% cost than natural gas, 70% than oil, and 85% than electricity!
 
Applicable materials: sawdust, wood shaving, bamboo dust, rice husk powder, palm shell powder, etc.
Raw material requirements: moisture ≤ 20%, size ≤ 3mm
 
Features
1
Plc intelligent control, one-key start, automatic switching of large, medium and small fires, fully automatic feeding.
2
The whole body is poured with special high-alumina refractory material, which is cooled by water and has a service life of more than 8 years, which is 5 times that of similar products.
3
Designed for industrial use, 24 hours continuous operation.
4
Fast cost recovery, investment with tens of thousands of Dollars, and annual cost saving of several million Dollars.
5
The calorific value of a single machine can reach 18 million kcal, and the corresponding boiler capacity is 30 tons.
6
Meet environmental standards, low emissions of nitrogen oxides, sulfur dioxide, dust in the flue gas.
