Industrial horizontal type coal/biomass boiler has a large furnace, achieves sufficient combustion and excess output. Sitong horizontal boiler realizes almost zero pollution with the use of special dust collector solution, it is honored as Chinese famous brand. The combustion equipment could be chain grate, moving grate, fixed grate and reciprocal grate, (small scale flaker is available), based on different fuel types and customers requirement, Sitong Boiler could design the specific grate individually. The fuel available for the horizontal boiler could be II class bituminous coal, biomass pellet, wood chips, rice hull, bagasse, straw, peanut shell, mustard stalk, cotton stalk, coconut shell, and waste cloth, etc.

Peculiarities of Sitong Industrial Horizontal Boiler

1. By using spirally corrugated tubes, the boiler has excess output. Generally, the actual output is 10~15% higher than it shown on the nameplate.
2. The temperature rise up quickly with high thermal efficiency (83%).
3. Low original emission concentration of smoke, energy saving and environmental protection.
4. The 100% NDT make sure the boiler life span more than 20 years.
5. Based on customers’ requirement, the combustion equipment can be designed as chain grate, moving grate, fixed grate, and reciprocal grate.
6. Sitong Boiler has got CE certificate of the industrial horizontal boilers, also, we can offer SGS, BV inspection.

Design and Configuration of Horizontal Boiler
Advanced Design and Configuration Function / Advantage
New Dust Collection Achieve almost zero pollution
Smoke and Dust Separation Chamber Decrease the original emission concentration of smoke
Splayed Wall Has the function of dust suppression, protect environment
Small Scale Flaker Type Grate New metallurgy formulate make the grate withstand high temperature more than 1600℃, make sure running without stop even when repair.
Spirally Corrugated Tube Improve heat transfer coefficient, thermal efficiency increase to 83%.
Airfoil Shape Flue Decrease the flue gas temperature in the area of high temperature tube plate, prevent tube plate cracking and swell.
Spark Retaining Wall in Furnace Improve the combustion efficiency.
New Type Furnace Arch Strength combustion, improve the adaptability of different coal types, and improve combustion efficiency
Header Backwater Ejection Avoid water wall tube crack
Secondary Air Design (Biomass Boiler Only) Improve the combustion efficiency and reduce emissions
