Description
Technical field
The present invention relates to a kind of electric heater, especially a kind of gas turbine nozzle electric heater.
Background technique
Gas turbine work, is the atomized fuel that sprays into firing chamber by lighting nozzle, and gas expansion for doing work is realized.Therefore the abundant degree of oil inflame affects the indexs such as the power of gas turbine.Fuel oil is in combustion process, and 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, first it is carried out to preheating, will be helpful to the power of raising gas turbine.The mode of the current intensification for flowing medium, guarantor's mild heat is a lot, but all there is the shortcomings such as structure or complexity or volume are excessive, heating-up temperature controllability is not strong, be not suitable for the heating of fuel oil, still belong to blank for the mode of heating of gas turbine fuel oil.
Summary of the invention
The object of this invention is to provide a kind of gas turbine nozzle electric heater, can carry out preheating to the fuel oil of gas turbine, and there is the features such as simple in structure, volume is little, temperature controllability is good.
Concrete technological scheme of the present invention is, gas turbine nozzle electric heater comprises fuel-intake connection, electric heating swivel nut pipe, porcelain tube, resistor rod, resistance wire, described electric heating swivel nut pipe is cylindrical shape, the oral area of cylinder is arranged on fuel-intake connection, bottom is provided with oil outlet, porcelain tube is cylindrical shape, be arranged on electric heating spiral shell inside pipe casing, two end faces contact with fuel-intake connection with electric heating swivel nut pipe interior bottom portion respectively, in porcelain tube, be also provided with resistor rod and resistance wire, resistor rod one end is positioned at electric heating swivel nut pipe interior bottom portion, the other end passes fuel-intake connection and fixes with tenminal block, resistance wire is distributed between resistor rod and porcelain tube twist, one end is connected with resistor rod, the other end is fixed on fuel-intake connection, in described fuel-intake connection, oil circuit is set, communicate with fuel path and electric heating spiral shell inside pipe casing respectively.Between described fuel-intake connection and resistor rod, be provided with O-ring seal.On described fuel-intake connection, be also fixed with electric-heating sheath, electric-heating sheath is positioned at resistor rod and passes the outside of fuel-intake connection part, and end is provided with electric heating nut.
The present invention installs resistor rod and resistance wire in the cavity of fuel-intake connection and the formation of electric heating screwed pipe, Resistant heating after energising, and fuel oil enters cavity from fuel-intake connection, by supplying with oil nozzle from electric heating screwed pipe bottom after Resistant heating.This device can pass through the temperature of Control of Voltage resistance wire, thereby controls the heating-up temperature of fuel oil.That the present invention has is simple and compact for structure, volume is little, and the controlled feature of temperature, can realize the heating object of gas turbine fuel oil, in actual applications, respond well.
