The article identified the main directions for improving the efficiency of boiler plants in the agro-industrial complex. An assessment was made of the significance of various heat losses from their total value and it was concluded that heat losses with exhaust gases in most cases occupy the main place among the heat losses of the boiler. A calculation of fuel economy was carried out when using a plate heat exchanger at various outdoor temperatures.

A diagram and description of the operation of an air radiant heating system utilizing the heat from boiler exhaust gases is presented. The nature of heat load regulation is described. Equations are presented and the flue gas temperature at the heat recovery unit inlet is calculated. The dependences of flue gas flow rate in the heat recovery unit and changes in air temperature in the air heating system on the heating load are determined. Graphical dependencies of the resulting functions are shown.
