Abstract
The invention relates to a fuel nozzle. The fuel nozzle is characterized by comprising a shell, a fuel preheating device, an oil filter and an oil spray device, wherein the fuel preheating device, the oil filter and the oil spray device are sequentially installed on the shell, an oil circuit is arranged inside the fuel preheating device and communicated with the inside of the shell, a resistance wire is arranged inside the shell, the oil spray device is arranged on the end part of the shell, and fuel directly enters the oil spray device after passing by the oil filter. The fuel nozzle is simple and compact in structure, has characteristics of small size and light weight and is small in heat loss and also capable of effectively improving the combustion efficiency of the fuel.
Description
Technical field
The present invention relates to a kind of fuel nozzle.
Background technique
Engine operation is to spray into by lighting nozzle after the atomized fuel of firing chamber, and gas expansion for doing work is realized.Therefore the abundant degree of the burning of fuel oil affects the indexs such as the power of gas turbine.When oil inflame, the temperature of himself affects the sufficient combustion degree of fuel oil, and temperature is higher, burns more abundant.Therefore, before fuel oil is lighted, sometimes fuel oil is carried out to preheating, the fuel oil after preheating enters nozzle after will being filtered.Due to the special chemical character of fuel oil, in the time of preheating, temperature can not be too high, therefore for avoiding thermal loss, should dwindle the distance of Preheating unit and oil nozzle as far as possible.But because the fuel oil after preheating also will pass through filter, therefore make the distance of Preheating unit and oil nozzle excessive, and structure is comparatively complicated, quality is large, and main is that thermal loss is also larger, makes the DeGrain of preheating, affects the power index of motor.
Summary of the invention
The object of this invention is to provide a kind of fuel nozzle, have simple and compact for structure, quality is light, and has the advantages that thermal loss is little.
Technological scheme of the present invention is, fuel nozzle comprises housing, fuel-oil preheating device, oil filter and fueling injection equipment, described fuel-oil preheating device, oil filter and fueling injection equipment are arranged on housing successively, fuel-oil preheating device comprises fuel-intake connection, resistance wire, fuel-intake connection is positioned on housing, and inside arranges oil circuit and communicates with enclosure interior, and resistance wire is positioned at enclosure interior, resistance wire one end is positioned at fuel-intake connection position, and the other end is arranged on the position that oil filter is installed; Oil circuit fueling injection equipment is arranged on the end of housing, and fuel oil directly enters into fueling injection equipment after oil filter.On described fueling injection equipment, be provided with cap nut, on described cap nut, be provided with air flue.
The present invention is arranged on Preheating unit, oil filter and fueling injection equipment in a housing, has effectively shortened the distance of Preheating unit and fueling injection equipment, and the thermal loss of fuel oil after preheating is little, and has realized filtering function.Cap nut is positioned on fueling injection equipment; on the air flue of cap nut, can introduce cool air; cool air can carry out cooling to fueling injection equipment; the normal work of protection fueling injection equipment; simultaneously; cool air can also participate in the premix of fuel oil and air, makes fuel-oil atmozation more thorough, and combustion efficiency improves.The present invention is simple and compact for structure, has little, the lightweight feature of volume, and meanwhile, thermal loss is little, can effectively improve the combustion efficiency of fuel oil.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
