METHOD OF PROTECTION OF BOILER UNIT AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2000 - IPC

FIELD: heat-power engineering; boiler unit protection and control systems at simultaneous recording of their parameters in generating steam or heating water. SUBSTANCE: sequence of processing parameters is preset in accordance with signals stored preliminarily processing is synchronized by formed pulse sequence in real time; formed control signals and signals subjected to primary processing which are proportional to technological parameters of boilers unit are recorded in fixed energy-independent storage; time of appearance of these signals is also recorded. Device proposed for realization of this method includes digital storage unit, digital controllable filter and timer whose first outputs is connected with input of interruption computer unit and control input of digital controllable filter whose information input is connected to information output of computer unit and its output is connected to actuating unit and to second input of storage unit; second input of digital storage unit is connected with second output of timer; besides that, digital storage unit and computer unit are provided with read-out-recording output. EFFECT: enhanced operational reliability; enhanced efficiency due to recording technological parameters of boiler unit, enhanced efficiency of study of derangement arising in the course of operation. 3 cl, 3 dwg
