Description
Technical field
The utility model relates to a kind of electric heater, especially a kind of gas turbine nozzle electric heater.
Background technique
Gas turbine works, and is the atomized fuel spraying into firing chamber by lighting nozzle, gas expansion for doing work is realized.Therefore the abundant degree of oil inflame affects the indexs such as the power of gas turbine.In combustion, the temperature of himself affects the sufficient combustion degree of fuel oil to fuel oil, and temperature is higher, burns more abundant.Therefore, before fuel oil is lighted, first preheating is carried out to it, will be helpful to the power improving 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, the mode of heating for gas turbine fuel oil still belongs to blank.
Summary of the invention
The purpose of this utility model is to provide a kind of gas turbine nozzle electric heater, can carry out preheating to the fuel oil of gas turbine, and has the features such as structure is simple, volume is little, temperature-controllable is good.
Concrete technological scheme of the present utility model 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, resistor rod and resistance wire is also provided with in porcelain tube, 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.O-ring seal is provided with between described fuel-intake connection and resistor rod.Described fuel-intake connection is also fixed with electric-heating sheath, and electric-heating sheath is positioned at the outside that resistor rod passes fuel-intake connection part, and end is provided with electric heating nut.
The utility model installs resistor rod and resistance wire in the cavity that fuel-intake connection and electric heating screwed pipe are formed, and Resistant heating after energising, fuel oil enters cavity from fuel-intake connection, by supplying oil nozzle after Resistant heating bottom electric heating screwed pipe.This device by the temperature of voltage controlled resistance silk, thus can control the heating-up temperature of fuel oil.The utility model have simple and compact for structure, volume is little, and the feature of temperature-controllable, can realize the heating object of gas turbine fuel oil, in actual applications, respond well.
