Basic Introduction

  • Yuanda DZL coal boiler, is a horizontal automatic boiler, water and fire tubes with alloy chain grate; It is a compact industrial boiler, three pass wet back structure, fuel is burning on the chain grate stoker.

  • It mainly includes coal steam boiler, coal hot water boilers and vertical coal boiler. Which are widely used in food, beverage, dairy, feed mill, oil refinery, concrete, textile, wood, papermaking, packaging, pharmaceutical, chemical, hotel, resort and many other factory.

  • DZL coal fuel boiler, steam boiler, coal hot water boiler

  • DZL packaged boiler, is a kind quick fitting single drum boiler. Automated ash removal, cast refractory ceramic lining, water back protection with reversal chamber, all make boiler high efficiency and long lifetime; PLC control, interlocking alarm, one worker can operate it well.

  • DZL boiler has the features of  "two wings-shape flue" "convex tube plate" "furnace arch" "inertia gas-dust separation" etc, realize high efficiency and low emission. It make DZL coal boiler superior, called as "Revolution of Industrial Boilers" by China and overseas markets.

  • DZL coal boiler with accessories

  • Yuanda Boiler provide clients with the support and expertise necessary to design, fabricate and install complete boiler system, from the fuel, boiler, and other accessories. Various industrial boiler design are suitable pressure for 4 to 38bar(50 to 500 PSI)



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


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


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


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
