Core Viewpoint - Zhongke Environmental Protection announced on September 18 that its turbine units for waste incineration projects include three types: pure condensing, extraction condensing, and back-pressure units, each capable of providing heat [2] Group 1: Turbine Unit Types - Back-pressure units have the highest efficiency but are limited by variations in thermal load, with electrical load changing in tandem with thermal load [2] - Extraction condensing units offer flexible power and heat adjustments and have relatively high efficiency [2] - Pure condensing units provide minimal heating and rely on temperature and pressure reduction for large heating, achieving high power generation efficiency but low heating efficiency [2] Group 2: Project Development - The company's Shijiazhuang project utilizes a pure condensing unit and is currently undergoing turbine unit modifications to enhance thermal energy utilization efficiency, which is in the bidding stage [2]
