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.
