Harbin heating boiler, CWRG series of coal-fired heating boilers with horizontal internal combustion three return combustion, ie the typical "S" type fire road, increasing the heating surface, improved thermal power. In the low-temperature flue section is disposed a considerable amount of the superconducting phase transition heat pipe, to fully absorb the die in the heat, greatly improving the thermal efficiency of the boiler, saving energy. As CWRG series Harbin water heating boiler with a sandwich, water pipes, heat pipe design superconducting phase transition, therefore, boiler heating, heating up fast. Our factory provide installation drawings and technical guidance to the user during installation, use the process without security risks and worries. Even the best products, after prolonged use, the furnace will cause excessive accumulation of dust thermal efficiency of the boiler itself is greatly reduced. So this product is designed cleaning open in the front door, simple and quick. Bright Harbin Boiler Factory was founded in 1993, from the birth of the first light the boiler starts, and now a series of atmospheric energy scattered coal boilers, pressure energy saving boilers, pressure steam boilers, pressure coal-fired boilers, heat water boilers, heating boilers, automatic brick machine, heating boilers, vertical steam boilers, horizontal steam boilers, coal-fired steam boilers, etc., after 10 years of efforts of all staff, from small to large, from weak to strong, is rely on sound detection means, advanced technology and equipment, excellent product quality and the pursuit of excellence, personalized service concept, the majority of user acceptance.
