Waste Heat Recovery Installation Notes: 1, the installation process, each flanged pipe mouth must strictly follow the label on the device corresponds to this connection. 2, the installation process, connect the flue and equipment should be avoided right angle bend connection. 3, the installation process, the water pump and each valve must be installed correctly. This equipment must be level with the ground must ensure installation. Flue gas heat recovery pathway usually two ways: one is to preheat the workpiece; two kinds of combustion air is preheated. Preheat the workpiece to be occupied by smoke large volume of heat exchange is often restricted job sites (intermittent use of kilns can not use this method). Preheat combustion air is a better way, generally arranged on the furnace can also be enhanced combustion, furnace heating rate of speed up and improve the thermal performance of the stove. This will not only meet the technical requirements, and finally obtain significant overall energy savings. Also from the beginning of the fifties domestic use in the industrial furnace preheated air preheater, mainly in the form of a tube, radiant and cast iron cylinder blocks and other forms of heat, but lower exchange efficiency. Eighties, the country has developed a jet stream, jet radiant, complex desktop and other heat exchangers, mainly to solve the low temperature waste heat recovery. Flue gas heat recovery and achieved significant results in 100 degrees, increase the heat transfer efficiency. However, at elevated temperatures due to the heat exchanger material constraints, low-life, maintenance workload or solid expensive and affect widely used. The early 21st century domestic production of the ceramic heat exchanger. Its production process and kiln production process is basically the same, thermal conductivity and oxidation resistance properties of materials is the main application. Its principle is to place the ceramic heat exchanger in the flue outlet closer, warmer place, no mixed with cold and high temperature protection, when the furnace temperature of 1250-1450 ℃, the flue outlet temperature should be 1000- 1300 ℃, the ceramic heat exchanger recover heat up to 450-750 ℃, the recovered hot air into the furnace and the combustion gas mixture formation, energy savings of 35% -55%, which directly reduce production costs, increase economic efficiency.
