Air Heat Exchanger as the Flue gas energy saver or Air preheater
What is the fuel gas energy saver?
Flue gas is the main way to waste energy in energy-consuming equipment. Flue gas waste heat recovery is mainly to convert the heat carried by flue gas into heat that can be used through some kind of heat exchange. There are mainly two forms of heat exchange: gas-liquid and gas-gas.
What are the features of air heat exchanger?
1. Energy-saving efficiency of 10-15% or more
2. Corrosion-resistant steel, life expectancy of more than 10 years
3. High heat transfer efficiency, efficient recovery of heat in low temperature flue gas
4. Low ventilation assistance of the equipment, can keep the original boiler operating condition unchanged
5. Widely used in various industrial furnaces, petroleum and petrochemical industry waste heat recovery
6. Can be designed according to user's specific conditions
7. Easy to install, safe and reliable, long service life, good energy efficiency, short payback period.
What is the energy-saving technology?
Boiler energy-saving technology includes: boiler flue gas waste heat recovery, boiler body heating surface and fan transformation, boiler operation optimization adjustment.
Among them, the flue gas waste heat recovery technology is more mature and the energy saving is considerable. The principle is to use heat exchangers to recover the heat from the flue gas and improve the efficiency of the boiler. One of the more advanced composite phase change heat exchanger, for most boilers can achieve a significant reduction in flue gas temperature, recovery of its heat to heat condensate, boiler make-up water, domestic water, etc., to achieve energy recovery and efficient use.
