Biomass Energy Thermal Water Pump
The objective of this research was to study a biomass energy thermal water pump (BTWP) in order to produce hot
water. The BTWP was powered by vapor which was obtained thermal energy from a cookstove. The mangrove charcoal was
used as fuel. The pump comprised an overhead tank (OT), liquid piston tank (LT), heating tank (HT), storage tank (ST), water
cooling valve (WCV) and well tank (WT). The pump could operate automatically. The overall water heads of 3 and 4 m were
tested. It was discovered that the pump efficiency was 0.0021% and 0.0048% depending on the overall water head. The
pumped water volume was same 70 l within 1 h. The pump starts working at temperatures in the LT equal to 102°C. The
average temperature of pumped water was around 42.8–44.9°C, which is sufficiently high for residential use.
