Introduction

  • Chain grate boiler is a horizontal three pass, fully wet back design, water&fire tube packaged type steam boiler with grate stoker. Capacity: 1 to 40 ton, 60hp - 2500hp; Pressure: 0.4mpa, 0.7mpa, 1.0mpa,1.25mpa, 1.6mpa, 2.5mpa.3.0mpa, 3.82mpa. which can burn wood, coal, biomass solid fuel, economical and 100% safe. It has strong fuel adaptability, automatic feeding, automatic slag removal, chain alarm, and convenient maintenance.

  • Chain gate boiler has the advantages such "three pass wet back" "two wings-shape flue" "convex tube plate" "special furnace arch design upon fuels" "inertia gas-dust separation" "reversal chamber" etc, realize high efficiency and low emission. It's called as "Revolution of Industrial Boilers" by China and overseas markets

  • DZL series chain grate boilers will be special furnace designed on the basis of different fuels used by customers. Such as coal, wood chips, rice husks, pellets or palm husks, bagasse etc

  • And we also have other grate type boiler: Traveling grate, Fixed grate, Reciprocating grate. Please share your fuel rate, we will choose the suitable boiler model for you.


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
