Abstract

ВОЗДУХОПОДОГРЕВАТЕЛЬ, содержащий воздуховод, установленную по оси камеру сгорани с входным и выходным патрубками, и двухходовым противоточный конвективный теплообменник, сообщенный с воздуховодом при помощи воздущных каналов , причем воздуховод и теплообменник подключены соответственно к низконапорному и высоконапорному вентил торам, к последнему из которых со стороны нагнетани подключен входной патрубок камеры сгорани , а выходной патрубок последней подключен к межтрубному пространству теплообменника , отличающийс тем, что, с целью снижени коррозии и улучщени качества сгорани , высоконапорный вентил тор установлен между ходами теплообменника, причем во входном патрубке камеры сгорани дополнительно установлен подогреватель топлива , а перед высоконапорным вентил тором - регулируема заслонка.An AIR submersible heater containing an air duct, an axially mounted combustion chamber with inlet and outlet nozzles, and a two-way countercurrent convective heat exchanger communicated with the air duct using air ducts, the air duct and the heat exchanger being connected respectively to the low-pressure and high-pressure ventilators connected to the air duct and the heat exchanger, respectively, to the low-pressure and high-pressure ventilators connected to the air duct and the heat exchanger respectively to the low-pressure and high-pressure ventilators connected to the air duct and the heat exchanger respectively to the low-pressure and high-pressure ventilators connected to the air duct and heat exchanger, respectively, to the low-pressure and high-pressure ventilators connected to the air duct and to the heat exchanger respectively to the low-pressure and high-pressure ventilators connected to the air duct by means of air ducts, the duct and the heat exchanger are connected respectively to the low-pressure and high-pressure ventilators connected to the air duct by means of air ducts respectively, to the low-pressure and high-pressure ventilation the inlet pipe of the combustion chamber is connected, and the outlet of the latter is connected to the annular space of the heat exchanger, characterized by o, in order to reduce corrosion and uluchscheni combustion quality, high-pressure fan mounted between the heat exchanger passages, wherein the inlet pipe of the combustion chamber fuel heater additionally installed, and before the high-pressure fan - the adjustable flap.
