Abstract

A novel combustion chamber comprises an oil jet nozzle seat, a combustion chamber housing, a front air barrel, a rear air barrel and a butterfly-like air plate, wherein an air channel is arranged between the combustion chamber housing and the front air barrel and the rear air barrel; the oil jet nozzle seat is fixedly connected to the combustion chamber housing and the front air barrel, respectively; an oil jet nozzle is provided with an air inlet on which a plurality of vortex plates are evenly distributed; the rear air barrel is provided with a plurality of rear air barrel front-section airinlets and a plurality of rear air barrel rear-section air inlets, respectively; a plurality of air curtain holes are formed on the bottom of the butterfly-like air plate; a plurality of reflecting holes are formed on a side wall, facing the direction of the front air barrel, of the butterfly-like air plate; and a heat-resistant alloy fibre evaporation mesh is jointed on the internal surface of the front air barrel. The novel combustion chamber of the invention allows the air to enter the combustion chamber via the reflecting holes in a direction opposite to the direction of a combustion gas flow in the combustion chamber, so that the turbulence condition of a fuel-oil mixed gas is evener and more rational. Moreover, the heat-resistant alloy fibre evaporation mesh improves the atomizationdegree of the fuel oil and promotes the secondary evaporation of the wall-attached fuel oil, so that the combustion efficiency can stably reach 95% or higher; therefore, the energy-saving effect is very obvious.

Description

technical field [0001] The invention relates to a combustion chamber, in particular to a combustion chamber. Background technique [0002] The combustion chamber is a key device of an oil-fired boiler or an oil-fired heater. The combustion efficiency of the combustion chamber is directly related to the performance of the oil-fired heating device. In the working process of the existing combustion chamber, the air supply method is not perfect and the fuel atomization is not sufficient, so the burning flame is too long, the combustion efficiency is low, and the volume of the combustion chamber is relatively large. Contents of the invention [0003] In order to improve the air supply mode of the combustion chamber, improve the atomization effect of fuel oil, and improve the combustion efficiency of the combustion chamber, the present invention proposes a combustion chamber, and the adopted technical scheme is: [0004] Combustion chamber, including fuel injector seat, combust...
