Plateau type fuel oil burner with high injection smoke and design method

Abstract

The invention relates to the technical field of burning equipment, in particular to a plateau type fuel oil burner with high injection smoke and a design method. The plateau type fuel oil burner withthe high injection smoke comprises an atomizing nozzle, a flame stabilizing disc, a burning cylinder and a burning cavity, wherein the atomizing nozzle is located in the middle of the flame stabilizing disc; the burning cylinder is arranged at the outer side of the flame stabilizing disc in a sleeved mode; the burning cylinder is arranged in the burning cavity; and a heat storage material is laidat the inner side of the burning cavity. The plateau type fuel oil burner is provided with the low-pressure air auxiliary atomizing nozzle, and the problem that a mechanical atomizing nozzle is poor in atomizing effect in the plateau alpine environment is solved; the burning cylinder structure is designed by adopting a high-temperature smoke self-circulation technology, so that the high smoke circulation rate of a burning chamber is realized, and the problem of high combustion pollution emission is solved; the blade type rotational flow flame stabilizing disc with small flow resistance is adopted to stabilize flames; and the heat storage material adopted to strengthen fuel oil burning, and the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a plateau type fuel burner with high smoke emission and a design method. Background technique [0002] In plateau and alpine regions, the environmental parameters change greatly, the oxygen content is low, the temperature is low, the air pressure is low, and the air supply volume of the fan is not enough, which will lead to problems such as difficulty in ignition of ordinary burners, reduced combustion power and efficiency, and high pollution emissions. Even if the air volume can meet the requirements of the air-fuel ratio, in view of the increasingly stringent environmental protection requirements in my country, many plain burners cannot achieve efficient and clean combustion in the plateau environment. [0003] Most of the existing commercial burner nozzles are pure pressure atomization or dual-fluid nozzles. The use of pure pressure atomization nozzles in the plat...
