WIPO Patent Application WO/2018/099346
Kind Code:
A1
Abstract:
Provided are a low calorific value gas power generation method and system, comprising the following steps: 1. sending low calorific value gas to a boiler (1) for combustion, and the flue gas generated by the combustion is heat exchanged with the heat exchange surface in the boiler (1); superheated steam of high temperature and high pressure is generated in a superheater (13), and the superheated steam is sent to a high pressure cylinder (21) of a steam turbine (2) for power generation; 2. the steam from the high pressure cylinder (21) enters the reheater (14), and the reheated steam enters a low pressure cylinder (22) for power generation; 3. the steam from the low pressure cylinder (22) after being condensed enters an economizer (15), and the water from the economizer (15) enters a boiler drum (12); and 4. in the boiler drum (12), the water enters a water-cooled wall (17) of the boiler (1) and is heated to a steam-water mixture and returns to the boiler drum (12); and saturated steam enters the superheater (13).
