  • Types of Boilers We Offer:

  • related industrial hot water boiler



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, 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
