Problems solved by technology

In the 1950s and 1960s, people began to apply pulsating combustion technology to heating and heating. Lucax-Rotax pulsating combustion hot water boilers were launched in Canada, but due to the low fuel price at that time and the excessive noise of pulsating combustion hot water boilers, etc. , preventing it from being promoted

Abstract

The invention discloses a pulsating fluidized bed combustion apparatus. It includes: acoustic decoupling chamber. Reike tube type pulsating fluidized bed combustion chamber main body is connected with acoustic decoupling chamber; airing plate is set at L / 12-3L / 4 position of the pulsating fluidized bed combustion chamber. L is the length of the combustion chamber main tube. Heating device is installed at the outer side of main body wall of pulsating fluidized bed combustion chamber. The heat exchanging surface is set at the inner or outer wall of the upper of the pulsating fluidized bed combustion chamber main body. The feeding device is installed at the side wall of the pulsating fluidized bed combustion chamber main body between heat exchanging surface and heating apparatus. The invention combines the pulsating combustion technique with fluidized bed combustion technique. It's a novel combustion conception.

Description

technical field [0001] The invention relates to a combustion device, in particular to a pulsating fluidized bed combustion device. Background technique [0002] Pulsating combustion describes the combustion process that occurs under the condition of airflow parameters, that is, state parameters in the combustion zone, such as temperature, pressure, speed, etc., which fluctuate periodically with time. The development of pulse combustion technology has gone through a long iterative process. In 1900, Gobble applied for the first German patent for a pulsating combustion device, but the structure of its air circulation control mechanism was too complicated to be put into practical application; in 1906, Esnault-Pelterie applied for a mechanical diaphragm self-excited oscillating pulsating burner French patent, its essence is a device that uses a pulsating burner to drive a gas turbine; in 1908, Lorin designed a pulsating combustion jet engine; in 1909, Marconnet developed an aero...
