Organic waste fermentation plant for methane fuel gas prodn. - uses prefabricated vessels for successive aerobic and anaerobic process stages

摘要

In the parent patent prodn. of a flammable gas, esp. methane, comprises fermentation of organic matter esp. agricultural waste. The gas is used at a heating and motive power fuel for houses, farms and small settlements requiring independence of external power supplies. In this addn. an installation for producing methane gas comprises two industrially prefabricated fermenting vessels, one for first stage aerobic fermentation and the other for second stage anaerobic fermentation. Appts. is easily transported and installed from high quality, prefabricated vessels and equipment. The installation produces a regular flow of fuel gas of consistently high calorific value.
