    DZL Coal fired Steam Boiler

    Brief introduction

    DZL coal fired steam boiler is horizontal style, low pressure, single drum, fire and water tube structure, chain grate 
    steam boiler with coal, soft coal, lean coal, bituminous coal, anthracite coal, brown coal, blind coal as fuel. Fuel feeding method is automatic which saves a lot of labor.
     
    Application of DZL coal fired steam boiler

    DZL coal fired steam boiler is widely used in textile industry, chemical industry, pharmaceutical industry, paper mill, 
    laundry, food processing industry and other industries. It can offer hot water and heat for hotels, schools, colleges, 
    governments, residential buildings, hospitals, and so on.

    Characteristics of DZL coal fired steam boiler 

    1. The arched tube plate and screw thread smoke tube build up the boiler barrel so that the boiler has high heat 
    transfer efficiency, boosts fast, strong output and the smoke tube is hard to accumulate dust, these solve the problem 
    of tube plate crack.
    2. Eliminate the stagnant water area at the bottom of the boiler barrel, improve the water recycling effect, prevent the 
    boiler barrel bottom bulge.
    3. All welding combining are processed by large mechanical and high temperature region bundle special processing, 
    to ensure the welding quality and service life. Easy burning and adapt to various fuel such as: soft coal, anthracite coal 
    and biofuels.
    4. Compact structure, small size, saving construction investment, easy to install, can run after connecting the valve, 
    water, electricity and pipeline.
    5. Stable operation, easy to adjust, unique design of air prevention, can bank up a fire for a long time.
    6. It has a function of dust reduction, dust emission conforms to the environment standard.

    Technical characteristics of DZL coal fired steam boiler

    1. Be equipped with automatic cleaning device for coal feeding roller to make the coal feeding roller clean.
    2. The view angle of the sifter can be adjusted according to the humidity of coal and different particle size of coal, the sifter have vibration function to avoid the blocking.
    3. Be equipped with anti coal blockage equipment automatic protective device for coal blockage, once the branch of the rollers got stuck, the automatic protective device will operate, protecting the drive part and layered facilities.
    4. Be equipped with coal quantity adjustment plate, making coal quantity adjustment convenient and accurate.
    5. Be equipped with doors and holes on the coal bucket which are convenient for the examination and repair.
