This research aims to study the work and performance of pumps, thermal energy from biomass. The mangrove charcoal as fuel for heating. To produce steam to power the pump. Conducted at the height of the water was one meter. And the height of the water two and three meters. The pump includes a device main six parts cylinder steam tank propellant tanks, wells, water storage tanks, cooling water and charcoal. It was found that Water began driving the temperature inside the tank driving around 102.0 degrees Celsius. Can pump seventh round Within 1 hour The hot water for about 70 liters Fueling Biomass 500 grams every 15 minutes. The average heating value of 29.281 MJ per kilogram. And the efficiency of the pump Equal to 0.0021 and 0.0048% , respectively. The results show that. Variables that affect the performance of the pump is a high turnover in the water. The ambient temperature and heat to enter
the keyword. Pump heat / steam / coolant.
