Abstract

A supercharged boiler test stand is formed by a Roots blower, a combustor, a boiler, a turbocharger and a fuel pump. The Roots blower is connected to an inlet of the combustor via a tee-joint diverter valve. An outlet of a compressor is connected to one inlet of a tee joint. Another outlet of the tee-joint diverter valve is connected to a cooling air sleeve. The fuel pump is connected to the combustor. A first vent valve is arranged between the Roots blower and a check valve. A second vent valve is arranged between the compressor and the check valve. A hearth of the boiler is connected to a pressure sensor and a thermocouple. The outlet of the compressor is connected to the pressure sensor. A controller adjusts a flow of a flow adjustment valve of the fuel pump and a rotation speed of the Roots blower. Through structures of variable frequency regulation, valve adjustment and the like, a technology parameter of a flue gas entering into the turbocharger is accurately controlled. An auxiliary steam turbine is not need to be added and an excess steam line is not need to be constructed and production cost is greatly saved. And the Roots blower only needs to work when the supercharged boiler test stand is started. After a starting process is finished, the Roots blower can be closed so that energy consumption is saved.

Description

technical field [0001] The invention relates to a pressurized boiler test bench. Background technique [0002] The supercharged boiler is a boiler that uses a turbocharger instead of a turbo blower to deliver combustion-supporting air with a certain pressure and temperature to the boiler furnace. The supercharged boiler test bench is a platform for testing the characteristics of the supercharged boiler starting, burning and working. [0003] The turbocharger is composed of a flue gas turbine and a compressor. It uses the inertial momentum of the flue gas generated by combustion to drive the turbine, and the turbine drives the coaxial compressor. The impeller of the compressor is sent by the air filter pipe. The air is pressurized into the furnace. In order to enable the supercharged boiler to start in a cold state, at zero load, an auxiliary steam turbine must be installed because there is no flue gas generated by combustion; similarly, at low load, the amount of flue gas ...
