Coal fire water tube boiler(DZL series)

ZBG dzl series chain grate coal-fired boiler with two-wing flue technology as the core, with reliable operation, large output and high thermal efficiency.

Fuel:Bituminous Coal, Anthracite Coal

Structural advantage

  A single-return threaded pipe is arranged in the drum, and the water-cooled wall of the tube is installed on the left and right sides of the furnace, and the heat transfer effect is good.

  Two-wing flue is set to avoid tube plate cracks due to temperature stress

  The front arch inclination angle of 45° echoes the rear arch, forming a distinct inverted “α” flame, which is conducive to the burning of inferior coal.

  The bottom of the drum is hung with refractory bricks and does not accept high temperature flame radiation.

High thermal efficiency

  The middle partition wall structure is conducive to fly ash burning, increase the flue gas stroke, and increase the heat transfer in the combustion chamber

  Efficient and energy-saving enhanced combustion technology, and designed with large volume furnace and combustion chamber

  Threaded pipe structure, high heat transfer coefficient, low heat loss

Less environmental pollution

  Fuel burns adequately, low original emissions

  Dust collector, desulfurization device, denitration device, etc. effectively reduce atmospheric pollutant emissions


  ZBG dzl series chain grate coal-fired boiler is a fast-assembly water-fire tube boiler with two-wing flue technology as the core, has the advantages of compact structure, reliable operation, small volume, large output, fast boost and high thermal efficiency. DZL series coal-fired boiler adopts light chain grate, with high degree of automation, equipped with dust removal equipment, less environmental pollution, and has good comprehensive economic and technical indicators. The boiler could widely used in schools, textile mills, garment factories, printing and dyeing factories, restaurants, food factories, beverage factories, soy products factories, meat products factories, canneries, wineries, pharmaceutical factories, packaging plants, building materials factories, paint factories, swimming pools Such as enterprises and institutions.
