Power Dependence Analysis Electric Drives Of Draft Machines From Air Flow


The topic of improving the efficiency and quality of the combustion process in heating boiler houses is relevant for heat supply enterprises, in this regard, various methods of automatic regulation of parameters are introduced and applied. The work objective is studying the dependencies of power ratings of forced-draft fan electric drives on air parameters. The research result was the revealing of the dependency of outdoor air temperature and consumed power of forced-draft fans in a heating boiler plant. Its level was 0.85. The research showed that the draft efficiency decreases if air temperature at the inlet of forced-draft mechanisms decreases. We have revealed the regularities of impact of carried medium temperature onto air and gas volumes, and impact of the temperature factor onto determination of draft air flow rate and, consequently, power of forced-draft fan electric drives. The work revealed a correlation relationship between the temperature of the outside air and the power consumption of the draft machines of the heating boiler house. Thus, the performed calculations of dependencies of outdoor air temperature and consumed power of forced-draft fans, regularities of impact of the carried medium temperature on air and gas volumes in the course of operation of forced-draft fans in a heating boiler plant made it possible to draw a conclusion on the need for preheating of the air supplied to boilers, in order to increase operation efficiency of forced-draft fan electric drives, and thus to increase the thermal performance of the heating boiler plant.
