I. Equipment composition
The equipment system consists of 9 parts: belt silo, hammer crusher, bucket elevator, coal silo, disc feeder, furnace body, blower, slag remover, and electric control cabinet.
II. Working Principle
The coal is crushed to less than 10mm by the crusher, and then evenly fed into the combustion furnace by the disc feeder. The furnace is equipped with air distribution plates and hoods, and is covered with 0-3mm fine sand or ash. The blower blows primary wind (air) from the bottom of the furnace, and the wind speed is controlled between the critical fluidization speed (making the particles begin to suspend) and the carrying speed (the particles are blown away). At this time, the bed material presents a fluid state similar to "boiling" to form a fluidized bed. This gas-solid mixing method expands the combustion area by nearly 10 times compared with the layer combustion method, significantly reduces the oxygen diffusion resistance, and greatly improves the combustion efficiency.
This type of furnace is suitable for a variety of fuels such as bituminous coal, anthracite, lignite and coal gangue, especially for low-quality fuels with high ash content and low calorific value.
III. Application Industry
Coal-fired boiling furnaces are widely used in many industrial fields:
Metallurgical industry: used for heating and smelting various metal materials, such as steel, copper, etc.
Building materials industry: used as a heat source for dryers to dry various materials, such as cement, gypsum, etc.
Chemical industry: used for heating and reacting various chemical raw materials, such as the roasting process in sulfuric acid production.
Other industries: such as pharmaceuticals, food and other industries where high temperature heating is required.
