Low-temperature economizer- the re-heating
system of condensing water and heating-water
The heating system inside and outside of
plant, using waste heat of flue gas, improves the efficiency of dust remove,
saves water and power for desulphuration, and save coal for power generation.
Low-temperature economizer-
air heater
Using waste heat of flue gas to heat 1st
and 2nd air of boiler, effectively prevents low-temperature corrosion and block
from air preheater, and extend lifetime of air preheater.
High-efficiency heat transfer MGGH system
of series materials
To solve "Smog Rain" by using waste heat of flue gas, the cooler can be put in front of dust remover for improving dust remove, and put after dust remover for saving water and power of desulphuration.
GGH
of coal-fired desulfurization
The raw flue gas temperature of coal fired
boiler is about 120 to 140℃ before entering the desulfurization tower and the cleaning gas
temperature is about 35 to 45℃ after desulfurization. Due to low temperature of cleaning gas, if
direct discharge, a large amount of "white smoke" will
form in the chimney outlet. The heat pipe
GGH, heating the cleaning gas by the raw flue gas, heats the cleaning gas to 70
to 85 ℃, solves the problem of "white smoke" at chimney, and
reduces the raw flue gas temperature and volume to improve the efficiency of
desulfurization and water consumption.
Flow
field simulation of flue gas waste heat recovery system
The waste heat recovery system of flue gas,
through the overall numerical simulation analysis, and reasonable arrangement
of reverse flow facilities and heat transfer surface, make the flow field
distribution uniform and CV value from 0.15 to 0.3, to ensure the long-term safe
and stable operation of the overall system.
