Coal fired steam boiler Archives - Xinxiang Xinda Boiler Co., Ltd

DZL coal fired steam boilers, are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface,while the drum and the water walls on both sides from a radiation heating surface in the furnace.

1.Characeteristics Of DZL Coal Fired Steam Boiler

Durable and Long life time.
Enough steam output, less heat dissipation, high thermal efficiency, lowest consumption.
High efficiency dust collector, more Eco-friendly.
Full automatic control, Protection devices for overheating, over-pressure, lacking water, leak detection, flame-out
Automatic fuel feeding, automatic water feeding, automatic ash remove so on.

3. Application Of DZL Coal Fired Steam Boiler

DZL coal fired steam boilers are widely used for the following industrial production

Textile industry – dyeing machine, drying rooms, high temperature machine, resin setting machine.
Food industry – cooking, drying, vegetable oil refining.
Chemical industry – oil chemistry, polymer industry, reaction tanks, distillation, concentration.
Plastics industry – plastics fired, extruded shape.
Rubber industry – hot press, hot extent, extrusion, vulcanization molding, injection, etc.
Paper industry – drying, corrugated paper processing, calender, glue roller.
Wood industry – hot processing, heat setting.
Hotel – cooking, bathing, laundry, central heating, etc.

DZH coal fired moving grate boiler is single drum boiler with both water tube and fire tube, the combustion equipment is moving grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and spirally corrugated tubes in the drum are convection heating area. This coal fired moving grate boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The furnace structure is in reasonable arrangement to achieve high efficiency.

1.Features Of DZH Coal Fired Steam Boiler

Moving grate made of cast iron, large furnace design, manual stoker, good applicability of fuel, coal, wood, wood waste, biomass, etc. can be used as fuel for boiler.
Few moving parts, less investment, low operating costs, low maintenance costs.
Forced ventilation, pressure boost fast to make sure enough output.
Boiler is compact structure, easy to install, reducing the cost of the boiler room and installation cost.
Steam boiler is single drum design big water volume, ability to adapt to changes in load.
Sufficient combustion, large heating surface, boiler adopt efficient threaded pipe, so the boiler thermal efficiency higher than the national standard.
