COMPRESSING AND SUPPLYING DEVICE FOR HIGH HUMIDITY FUEL GAS

PROBLEM TO BE SOLVED: To provide a simple facility at a low cost with low power consumption for compressing and supplying high humidity fuel gas such as biogas to a microturbine generator. SOLUTION: The first characteristic of the compressing and supplying device is that high-humidity fuel gas compressed by a compressor 3 is cooled by a cooling-type fin tube-shaped radiator 6 having a simple structure, the moisture included in the fuel gas is condensed and liquified, most of the moisture is removed by a moisture removing means such as a gas-liquid separator 8 and an adsorption-type dehumidification tank 7, and the electricity needed is merely for driving a motor 6b of a cooling fan. The second characteristic is that the fuel gas with most of the moisture removed is delivered to a pipe 10 to the microturbine generator 12 after being heated in the heat exchanger 9 using compression heat generated in the compressor 3. Even when the fuel gas flowing through the piping 10 is naturally cooled, the remaining moisture does not become liquefied nor frozen. COPYRIGHT: (C)2004,JPO
