The CLSG vertical coal-fired atmospheric pressure hot water boiler adopts advanced combustion technology. Coal is input from the furnace door and burned on the grate. High temperature flue gas is flushed through horizontal water pipes in the furnace and enters the flue gas combustion chamber. Through high-temperature radiation, the flue gas and smoke are fully burned again, and the heat is fully absorbed and utilized before being discharged into the atmosphere. It is smoke-free, environmentally friendly, energy-saving, and highly efficient. The company has introduced German technology and obtained patents. Due to the fact that the hot water boiler operates without pressure, it can be installed anywhere without any restrictions, and does not require inspection restrictions from the supervisory department. This type of safe, reliable, and non explosive hot water boiler has been rapidly developed and promoted in recent years.

1. Compact structure, easy installation and migration, small footprint, and low infrastructure investment.
2. Longitudinal flushing of convective tube bundles by flue gas, secondary combustion technology of flue gas, fully utilizing the heating surface, and improving the thermal efficiency of the boiler.
3. Fast heating, fast water production, good heating effect, easy operation, etc.
4. The internal heating tube design is reasonable, and the boiler body is equipped with hand holes and manholes for easy maintenance.
