Diesel-Fired Self-Pumping Water Heater
Abstract
The object of this project was to study the feasibility of pumping and heating water by sustained ocillatory vaporization and condensation in a fired heat exchanger. Portable field liquid fueled water heaters would facilitate heating water for sanitation, personal hygiene, food service, laundry, equipment maintenance and decontamination presently, available only from larger, less portable, motorized pumping units. The technical tasks consisted of: development of an analytical model, operation of proof-of- principal prototypes, determination of the thermal and mechanical relationships to evaluate operating range and control characteristics. Four successive pump models were analyzed and tested. The final analytical model gave reasonable agreement with the experimental results, indicating that the actual pumping effect was an order of magnitude lower than originally anticipated. It was concluded that a thermally-activated self pumping water heater based on the proposed principle is not feasible.
