Product Introduction

Basic Principle Of Wood Dust Burner

Through the feeding device, the raw materials enter the fuel bin, then blowing into wood powder burner by air fan, Through high-temperature cracking and suspended semi-gasification combustion, and then transfer the heat to the energy-using equipment. Using the principle of radiant heat and convection heat, three-stage of air distribution and oxygen increasing to make wood powder fully burned in the furnace and more than 98% of heat is transferred to energy-using equipment.

Feedstock Of Wood Dust Burner

Types of fuel: wood powder, sand powder, rice husk powder, coal powder, etc.
Biomass fuel requirements: powder diameter 60-80 mesh, moisture content<15%
Coal powder requirement: calorific value>25MJ, volatile component>25%, ash content 8-10%, total moisture 3-4%, total sulphur<1%,
powder size 150-200 mesh

Wood Dust Burner Application: Used for Steam boiler, Thermal oil furnace, Rotary dryer, Spray drying line, Coal-fired boiler, Aluminum melting furnace, Incinerator, Forging heating
