Self lowering boiler gathering heat from depths of earth - comprises telescopic boiler unit fitted with offset bulkheads and additional heat sensor

摘要

Self-lowering boiler has bulk heads (3) positioned offset in the longitudinal axis between the outer pipe (6) and the inner pipe (7) of the hollow cylinder to ensure a complete circulation of the gas form media forced into the boiler along the whole inner walls of the boiler and at the same time bring about a temp. equalisation inside the boiler of any desired length. The boiler has a telescopic boiler unit. An additional heating sensor is located inside which can be regulated to gain energy from the interior of the earth.
