ffected Heat Pipe and Chimney to Performance of Boiler for Steamed Mushroom Bag

Abstract

This study was aimed to study the performance of mushroom steamed boiler. The boiler was double wall contained water to heat exchange in 3 conditions: 1) mushroom steamed boiler which having heat pipe at bottom of boiler 2) mushroom steamed boiler which having heat pipe at bottom of boiler and at the chimney 3) mushroom steamed boiler which having heat pipe at bottom and upper of boiler and at the chimney. The study factors were the amount of fuel consumption, the steam production rate and the thermal efficiency of mushroom steamed boiler. The water was vaporized in 180 minutes and Eucalyptus wood fuel was consistently feeded into the boiler. The performance results of the mushroom streamed boiler in 3 conditions showed that the fuel consumption of the 1st, 2nd and 3rd condition were 51.5, 50.7 and 49.8 kg (dry basis), respectively. The steam production rates of three condition were 17.7,20.8 and 22.0 liters per hour, respectively. The thermal efficiency of three conditions were 24.43, 29.04 and 31.16%, respectively.
