Why installing economizer in boiler flue only saves energy?

Generally speaking, the boiler heat consumption rate will increase by 1% when the exhaust gas temperature decreases by 15℃, but there is no more energy-saving space for boiler management, so it is impossible to break through the bottleneck and realize energy saving and consumption reduction. Energy consumption not only increases the fuel cost, but also increases the treatment cost before discharge, and also reduces the economic benefit of use efficiency.

If an economizer is added to the flue of the boiler and the waste heat recovery device is used as the heat source of hot water, the following benefits can be brought:

1, reducing the consumption of steam extraction in production and achieving the purpose of energy saving;

2. Recover waste heat to improve thermal economy;

3. Reduce coal consumption, and at the same time reduce the economic cost of coal treatment and emission;

4. Save water and electricity;

5. Selling hot water increases income.
