Abstract
The invention relates to a boosting control type flue gas channel waste heat recovery system. The boosting control type flue gas channel waste heat recovery system comprises a boiler and a waste heat exchanger which are mounted the ground. A flue gas outlet of the boiler is connected with the waste heat exchanger through a first flue gas pipe. An outlet of the waste heat exchanger is connected with a second flue gas pipe. An economizer is mounted on the second flue gas pipe and is connected with a feed water pump through a water inlet. A steam outlet is formed in the top of the waste heat exchanger. A pressure detection point is arranged on the first flue gas pipe and connected with a gas-pressure sensor. The output end of the gas-pressure sensor is connected with a controller of the waste heat exchanger. A first boosting pump is connected to the first flue gas pipe through a branch pipe. A second boosting pump is connected to the second flue gas pipe through a branch pipe. The waste heat exchanger comprises a flue gas channel. A snake-shaped pipe is arranged in the flue gas channel. The vertical section of the snake-shaped pipe is sleeved with a fume suction pipe.
