Introduction

  • Yuanda DZL SZL chain grate boiler is a horizontal boiler, three pass, water-fire and water tube boiler. It is the packaged quick fitting industrial boiler. Boiler capacity: 1 ton ~ 40 ton, 60hp 2500hp, the maximum pressure of chain grate boiler can reach 3.82 Mpa / 450℃, widely used for factory processing or drive steam turbine.

  • Design Fuel: coal, biomass, palm shell, wood chips, biomass pellet, cashew nut, rice husk, wood waste/shavings, sawdust etc. Yuanda Boiler good at chain grate boiler furnace design, different fuel design different furnace according to fuel characteristics;

  • DZL SZL chain grate boiler, coal chain grate boiler, biomass grate boiler

  • DZL SZL chain grate boiler, is our company patent feature product. This boiler has the characteristics of ①15% bigger furnace combustion, the heated area increases by 40% ②Light furnace wall, not easy to collapse, good airtightness, no deformation, no dust falling; ③The best adjustability, segmented air supply (preheating zone, drying zone, main combustion zone, coke zone, ash slag zone) can freely adjust the air volume ④ Secondary cyclone burnout chamber, greatly reduce fuel cost, improve boiler thermal efficiency ⑤ Built-in dust removal device in the furnace, effectively solve the problem of coking. It's called as "Revolution of Industrial Boilers" by China and overseas markets.

  • biomass fired chain grate boiler, reciprocating grate boiler

  • YUANDA BOILER has other fixed grate boiler, moving grate boiler, reciprocating grate boiler, please ask any question you may have.

Characteristics

01


Three pass gas flue structure & Arched tube plate

1. Three pass design extends the flue gas distance, strengthen the thermal transfer efficiency; 2. Arched tube plate increases the toughness of the tube sheet, prevent end cover cracking


02


Spiral Fire Tubes(Smoke Tube) Technology

Use the advanced technology which is our patent to design the spiral tubes, to enhance the boiler thermal power 10% higher than normal, and avoid the spiral tube from ash deposition and wearing


03


Fully automatic chain grate combustion

Use big piece fire grate, air supply sufficient and evenly, tight connection, almost no leakage, avoid loss of calorific value and affect boiler thermal efficiency


04


Economizer Design, Energy Saving

1. Recycle exhausted smoke to heat feed water, increase feed water temp then save fuel cost at least 6% per hour 2. Reduce chimney smoke temperature
