Problems solved by technology

[0004] In terms of waste heat utilization of waste flue gas, after the waste flue gas passes through the waste gas switch, the temperature of the flue gas is about 280°C, and the temperature of the flue gas is very low. Using a conventional heat exchange device to generate low-pressure saturated steam requires a large investment in the waste heat system. The generated low-pressure saturated steam has few uses and low value, which makes the waste flue gas waste heat recovery project less economical
[0005] The current technical solutions divide the sensible heat of raw...

Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the embodiments of the present invention are further described in detail:

[0019] This embodiment provides a power generation system that jointly utilizes the sensible heat of coke oven raw gas and the waste heat of waste flue gas.

[0020] The exhaust gas system is used to lead the coke oven exhaust gas through the coke oven flue into the waste heat boiler system;

[0021] The coke oven exhaust gas is drawn from the coke oven flue, enters the waste heat boiler, passes through the waste heat boiler evaporator, waste heat boiler economizer, and then returns to the original exhaust system of the coke oven through the boiler outlet through the induced draft fan.

[0022] The raw gas system uses low-pressure steam as the cooling medium of coke oven raw gas to absorb the sensible heat of raw gas;

[0023] Coke oven raw gas collects at the top of the coke oven and enters the r...

Abstract

The invention discloses a power generation system capable of jointly using sensible heat of raw gas of a coke oven and waste heat of waste smoke, which can utilize low-quality waste heat of waste smoke to produce low-pressure saturated steam and use low-pressure steam as cooling media of raw gas of the coke oven to absorb sensible heat of raw gas to produce high-quality superheated steam which is used for generating power. The power generation system changes technical limit that presently two waste heat resources are recycled independently, improves using value of the low-pressure saturated steam generated by the waste heat of the smoke, provides ways for the low-pressure saturated steam generated by the waste heat of the smoke, duly resolves the problems of water leakage, tar condensation, ascending pipe plugging and the like in recycling of the sensible heat of the raw gas, and remarkably improves using efficiency and economic value of waste heat resource of the coke oven.

Description

technical field [0001] The invention belongs to the field of utilization of coke oven waste heat resources, in particular to a power generation system for jointly utilizing the sensible heat of coke oven raw gas and the waste heat of flue gas. Background technique [0002] There are three main waste heat resources in coke oven production, namely red coke sensible heat, raw coal gas sensible heat and waste flue gas waste heat. Among them, CDQ technology for recovering the sensible heat of red coke has been promoted, but the utilization of raw gas sensible heat and waste flue gas waste heat has not been widely used due to technical difficulties and poor economic efficiency. [0003] In terms of sensible heat treatment of raw coal gas, the process generally adopted by coke ovens at home and abroad is to collect the raw coal gas generated during the carbonization process in the carbonization chamber into the top space of the carbonization chamber, and enter the gas collecting pi...
