Abstract

The research was carried out on a biomass boiler fueled by rice husks. The boiler unit uses two air sources, the first comes from groundwater which is treated at the softener plant and then stored in the make-up water tank. The second air source comes from the remaining condensation from machine production, which is then collected in the condensate tank. The biomass boiler uses rice husk fuel, with a low heating value, namely 14,600 kJ/kg. The density value of rice husk is 125 kg/m3. Water content with a value of 9% to 11%. Feed air originating from the condensation of the production process is channeled to the condensate tank. The air temperature in the condensate tank averages 35oC. Air feed from the condensate tank is pumped to the deaerator. To remove the O2 content in the deaerator, the deaerator temperature must be maintained at 95oC – 105oC. If the feed air temperature is low, more injectable steam will flow into the deaerator. If more steam is channeled to the deaerator, the combustion will be greater, and more fuel will be used. In this condition, the average efficiency value that appears is only 68%, with an average fuel consumption of 1.2 tons. The efficiency target is 83% with an average boiler load of 65% of maximum capacity. The improvement carried out was to increase the temperature of the condensate air, by injecting steam into the condensate tank. Results in an average feed air temperature of 76%. Under these conditions, the average fuel consumption used is 1.1 tons. And got an average efficiency score of 76%. Keywords: Boiler efficiency, boiler biomass, air feed temperature
