FIELD: heating. ^ SUBSTANCE: invention is meant for heating water and can be used in transport technology. Invented is an air heater used in transport with a burner and heat-transfer agent in it, device for controlling the burning of the burner flame and device for supplying heated air through the heat-transfer agent. The device for controlling burning of the flame is provided with a device for measuring temperature of the heated air, flowing through the air heater. The device for measuring temperature is supplied with the first sensor for measuring temperature of the air leaving the air heater. The device for measuring temperature can calculate the temperature gradient of the flowing heated air. The device for measuring temperature is provided with a second sensor for measuring temperature of heated air flowing into the heater. The device for measuring temperature can calculate the temperature gradient of the heated air flowing into the heater, and also the difference in the temperature gradients of the heated air flowing in and the heated air flowing out. ^ EFFECT: increase in efficiency and operational safety of the heater. ^ 7 cl, 1 dwg |
