FIELD: heating devices engineering. ^ SUBSTANCE: device has tank for heated liquid, feeding pipeline for heat carrier and adjusting circuit. Feeding pipeline has valve and temperature sensor. Adjusting circuit drives the valve. It also has limit frequency detector, which determines oscillations of temperature and adjusts force of back loop of adjusting circuit dependently on frequency. Method for operation of heating plant includes determining temperature of heated liquid. Feeding of heat carrier is adjusted on basis of oscillation of this temperature form given value. Also frequency of temperature oscillations is determined, and amplification of back loop is changed dependently of this frequency. ^ EFFECT: higher speed of operation. ^ 2 cl, 5 dwg |
