FIELD: mechanical engineering; air heater plants. ^ SUBSTANCE: proposed method of delivering heat carrier into air heater plant consisting of two or more air heaters installed in tandem in two or more rows in direction of air flow comes to connection of air heaters to supply and return heat carrier pipelines. At temperatures of ambient air ta.a>0°C counterflow-cross connection of air heaters according to heat carrier is done, and at ambient air temperature of ta,a,<=0°C, straight-cross connection of air heaters according to heat carrier is provided. ^ EFFECT: provision of reliable protection against freezing of air heater plants, reduced consumption of heat supply water. ^ 1 dwg |
