Flue gas waste heat recovery device:
Flue gas is the main way to waste energy in general energy-consuming equipment, for example, boiler exhaust energy consumption is about 15%, while other equipment such as the printing and dyeing industry's sizing machines, dryers and kilns are the main energy consumption through flue gas emissions. Flue gas waste heat recovery is mainly to convert the heat carried by the flue gas into usable heat through some kind of heat exchange.
The ways of flue gas waste heat recovery:
1.Waste heat recovery device (gas-water)
Waste heat recovery device is a special equipment for coal-fired, oil-fired and gas-fired boilers, which is installed at the flue mouth of the boiler to recover flue gas waste heat for heating domestic water or boiler make-up water. When working, the flue gas flows through the flue of the waste heat recuperator to scour the heat exchanger tube, and the heat of the flue gas is transferred to the water inside the heat exchanger tube, so that the water temperature rises. In order to prevent ash plugging and corrosion, the waste heat recovery device is generally made of stainless steel, and the boiler saves 4-18% fuel after installing the flue gas waste heat recovery device.
2. Waste heat recovery (gas - gas)
Waste heat recycler is fuel, coal, gas boiler special equipment, installed in the boiler flue or flue, the flue gas waste heat recovery after heating air, hot air can be used as boiler combustion and drying materials. The flue gas goes inside the pipe, and the fresh air outside the pipe. When working, high temperature flue gas from one side of the tube to the other side, fresh air flushing heat exchange tube, then the heat of the flue gas will be converted to fresh air through the heat exchange tube, the flue gas exothermic temperature drop. The cold air is heated up from the heat absorption.
Performance characteristics
1、Easy installation: The installation of waste heat recovery device does not require changes to the original boiler or industrial furnace.
2、Safe and reliable:The waste heat recovery device has good temperature resistance, small ventilation resistance when heat conduction Always maintain a good heat transfer efficiency, does not affect the work of the boiler or furnace.
3, long service life: waste heat recovery device service life of more than 5 years, stainless steel production to reduce the impact of flue gas corrosion.
4, good energy efficiency: large industrial furnace efficiency can be increased by more than 10%, small and medium-sized oil, gas, coal-fired boiler efficiency can be increased by energy saving up to 5%-10%.
