Boiler Applications
-Providing hot water for central air-conditioning system or radiators heating;
-Providing continuous hygienic hot water, together with water-water heat exchangers;
-Providing hot water for industrial process;
Product Features
-The mature three-pass, wet back and fire tube design;
-Corrugated furnace: increasing heating surface and improving efficiency;
- Round end plates (tube sheet): straight connection welding better than angle welding;
- Hinged smoke chamber door, big man hole and hand hole for easy maintenance;
-Multi-level sealing for smoke chamber: non flue gas leakage;
-100mm Aluminum silicate wool insulation material: less surface temperature and heat loss;
-Intelligent boiler controller consisted of Simens PLC and touch screen with full safety protections like water temperature, exit flue gas temperature, etc;
-Main components, such as burners, pumps, water level meters, valves are limited to qualified suppliers and renowned brands;
-Each boiler shall be subject to strictly inspection and testing before shipment, including
hydraulic testing , X ray inspection, factory test, etc;
-Boiler economizer is optional and possible to save 10% fuel and decrease noise 20 dB;
-Applicable fuels: gas, oil, dual fuel.
