FIELD: machine building. ^ SUBSTANCE: invention relates to installation for burning fuel and heating processing media that comprises burner, heater to heat product by combustion gas, blower, air heater, flue gas pump, flue and working medium feed and discharge lines. Note here that product heater and air heater are connected along flows of combustion gas flowing from the burner. They are made up of vertical cylindrical recuperative heat exchangers, each accommodating, at least, one radial heat exchanger. Branch pie to discharge flue gases form air heater is communicated with flue gas pump. Flue gas pump pressure line is divided into two flows. Note here that one flow communicated with flue while another flow communicates with air line upstream of blower. ^ EFFECT: lower costs and smaller production area, reduced consumption of fuel, higher reliability and reliability. ^ 7 cl, 2 dwg |
