Method and device for generation of thermal energy using vegetable oil, comprise intermediate use of buffer store

摘要

The circulation pump (21) and the water heater (19) are switched on first. Vegetable oil is burned in a forced draft burner (28) and the heated water sucked out of the heat exchanger (23) by the circulation pump (21) and pressed into the buffer tank (3). Water is simultaneously continuously guided from the buffer tank (3) via a primary circuit (2) to the heat exchanger (23) and reheated. When a preset temperature is exceeded the water heater (19) is switched off, the circulation pump (21) also, but after a short interval, and the water mixed inside the buffer tank (3). An independent claim is given for a unit generating thermal energy from vegetable oil.
