Abstract

The boiler includes parts: burner hearth structured in furnace as inner layer, boiler barrel as outer layer, and water-cooling jacket pipes in middle layer; convection bank of pipes composed of multiple pipes with helix fins; shell of pipe type device for reclaiming coagulation heat from flue gas. The invented boiler possesses features of compact structure, raising heat exchanger effectiveness between flue gas and working medium, absorbing coagulation heat in high efficiency and reducing temperature of exhaust fume. Based on need, the boiler can be ran in conjunction with gas turbine as waste-heat boiler without or with afterburning, or as independent boiler.

Description

technical field [0001] The invention relates to a high-efficiency multifunctional waste heat boiler with a micro gas turbine, which can also be called an energy island waste heat boiler, and belongs to a new type of boiler in the field of energy. Background technique [0002] The energy island is a combined electricity, heat, and cooling system (CCHP) composed of micro gas turbines, waste heat boilers, and generators. It is characterized by high energy utilization rate, compact structure, small footprint, short construction period, fast start-up, good peak-shaving performance, high degree of automation, and low environmental pollution. Waste heat boiler is a thermal energy utilization equipment that uses waste heat from various production processes to produce steam or hot water. Due to the different production processes, there are currently many types of waste heat boilers at home and abroad. Domestic waste heat boilers are mainly matched with large gas-steam combined cycl...
