1. large heating area 2. low coal consumption 3. high effeciency 4. long life time 5. easy for installation

Product Features:

1. The boiler uses natural ventilation to ensure fuel can burn fully, low noise, low invest.

2. Several fuels can meet customers’ different requirements.

3. Slip structure of heat exchange box makes big heat exchange area, high heat utilization, high heat efficiency.

4. Box type, small volume, occupies small space, low operation cost.

5. High standard insulation material reduces heat loss, and saves cost and sources of energy.

6. Simple structure, easy installation, and easy repair.

 

 

Combustion mode:

 

Atmospheric boiler uses double grates back-fire natural ventilation, coal burns on water-pipe grates, and flame goes through down water-pipe grates meet flame burned on cast iron grates. High temperature flame fires water pipes and exhaust from chimney on boiler top.
