DETERMINING THE DEPENDENCES OF ENERGY EFFICIENCY IN THE BOILER-ROOM WITH ITS OPTIMIZATION TO ENSURE THE ENERGY SAFETY OF THE PROCESS OF FUEL COMBUSTION
The technology of poultry dung burning in specialized water-heating and steam boilers, with the thermal utilization rate of one dung portion of about 10 - 15 seconds, is suggested to obtain an effective potassium phosphate fertilizer and to reduce secondary waste products and emissions concentration. A series of experiments purposed to study the effect of fuel feed rate (l/s), air temperature (°C) and hydrocarbon content in fuel (%) on noise load (dB), specific financial costs (rubles / kJ) and energy efficiency (kJ/kg ), when burning poultry dung, has been conducted. Taking into account the prevalence of the noise load and specific financial costs over energy efficiency, it has been concluded that the optimal air supply rate should be from 0 to 0.3 cu. (from 0.05 to 0.056 l/s), air temperature - from 0.1 to 0.4 cu (from 75 to 90°С). This will result in: energy efficiency of more than 450 kJ/kg, noise load of less than 61 dB and specific financial costs - of less than 5.2 rubles/kg
