Utility / HRSG / Package Boiler Economizer High Efficiency Reduce The Cost Export Germany


Exhaust heat loss is the largest of the heat loss of the power plant boiler, usually 5% to 8%, accounting for 80% of the total heat loss of the boiler or higher.
The main factors that affect the heat loss of the exhaust gas are the boiler exhaust temperature. Under normal circumstances, the exhaust heat temperature increases by 10 ℃ and the exhaust heat loss increases by 0.6% ~ 1.0%.

China's current thermal power units in the boiler exhaust gas temperature is generally around 125 ~ 150 ℃, the actual smoke temperature is higher than the design value is ubiquitous phenomenon.

Low temperature economizer

"Low temperature economizer", can greatly reduce the flue gas temperature, so that the flue gas temperature be reduced lower 40 ~ 50 ℃ or more.

The energy absorbed by the "low temperature economizer" can be used to heat the condensate or to increase the temperature of the combustion air by heating the air through the heater.

Power plant boiler using "low temperature economizer", can save 1 ~ 4g / kWh, unit efficiency increased by 0.2 to 1.2%. "Low temperature economizer" in the full recovery and utilization of exhaust heat at the same time, but also to achieve the best desulfurization efficiency of smoke temperature, greatly reducing the desulfurization tower to reduce the smoke and water spray cooling water consumption.

Under normal circumstances, it takes 1 ~3 years for power plant 1 to recover the investment in "low temperature economizer" and its system equipment , that is to say, the economic benefits are enormous.

Performance advantages

1.Application of flue gas waste heat recovery system for tail flue of power plant boiler

The thermal temperature is low, usually 100℃ or so with not good quality.

(1) This part of the recovery of heat is not equivalent to the method of calculation, but should be equivalent conversion method or heat balance calculation to determine the effective use of heat recovery value (thermodynamics second law).

2. Used in other industrial boilers in the flue gas waste heat recovery device

(1) Under normal circumstances, the economy is in priority in power plant application. This is because in other industrial boiler systems, the available steam resources are limited. For users with not enough steam, the recovery of heat can be considered 100% available resources, the most economical.

(2) flue gas waste heat exchanger advantages

improve the efficiency of recycling, reduce coal consumption;
improve the efficiency of dust removal (before the installation of dust collector);

reduce the evaporation of desulfurization tower, saving water.
