Brief Intro: :Horizontal type coal fired stoker boiler is shell type boiler with three-pass structure, the stoker could resist 1200℃,has low coal leakage, high automatic degree, and convenient maintain.
The horizontal type coal fired stoker boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.), it is honored as Chinese famous brand. This series boiler is shell type three-pass structure boiler with single drum or double drums. Generally, the steam capacity higher than 10t/h is designed as double drums to offer the sufficient output. The combustion equipment is stoker (small scale flaker is available), has the advantages of feed mechanically, strong adaptability of different fuels, low coal leakage, and convenient maintenance. The fuel is coal, the diameter should be 6-25mm, and ash content should be less than 32.4%.
This coal fired boiler uses the new scientific achievement, such as arch tube plate, spirally corrugated tube to solve the problem of low thermal efficiency, tube plate cracking, drum bulging, insufficient output, and environmental pollution. Sitong Boiler has a mature R&D and design team, could customize the boilers based on customers’ requirement.
1) The small scale stoker could resist the temperature as high as 1200℃, long working life.
2) The stoker has a low coal leakage because of the small gap.
3) High automatic degree, decrease labor cost.
4) Convenient for maintenance, it could be done without boiler shut down.
5) Based on customers’ requirement and fuel characteristics, the grate could be designed as small scale stoker, chain belt grate, bar grate, etc.
High thermal efficiency
1)The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.
2)The furnace wall was poured entirely by the heat-resistance concrete and high-temperature-resistance refractory brick, and the boiler shell use aluminium silicate board for heat preservation, low heat loss.
3) Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.
The riser tube bundle under the drum, remove the dead water region at the bottom of drum, sludge is not easy for depositing, the high temperature area of drum has better cooling, prevent bulging.
Avoid tube plate cracking
1) The boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress, solves the problems of tube plate cracking.
2) Arrange two sides gas duct in drum, the smoke gas could enter into the front smoke chamber smoothly, the temperature of tube plate is lower than 600℃, avoid cracking leaded by high temperature.
Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion, and the boiler could absorb the thermal expansion effectively. The large diameter boiler drum increases the radiant heating surface, to ensure the sufficient output.
1) The splayed wall and smoke outlet have the function of dust removal, decrease the concentration of smoke emission.
2) The moving grate boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.
