近年来,全国许多地区都在积极试验以红泥塑料薄膜为材料的沼气池,但是,由于目前还没有与之相配套的超低压沼气灶,所以至今很难推广应用。即使有些地区使用自己改装的沼气灶,由于燃烧器的引射管、头部及火孔等有关部位的尺寸都没有改变,因此存在着热效率低,烟气中一氧化碳含量过高,燃烧稳定性差等问题。为了给低压沼气池配套,解决低压沼气的利用向题,我所受全国沼气建设领导小组办公室的委托,继北京四型低压沼气灶研制成功以后,1982年又研制成
In recent years, digesters made of red clay plastic film are actively tested in many parts of the country. However, it is difficult to popularize biogas digesters so far because there are no matching ultra-low pressure gas stoves. Even if some areas use their own modified biogas stoves, the size of the relevant parts of the burner, such as the ejecting pipe, the head and the fire hole, has not changed, so there is a problem that the thermal efficiency is low, the carbon monoxide content in the flue gas is too high, and the combustion stability is poor problem. In order to support low-pressure biogas digesters, to solve the problem of the use of low-pressure biogas, I was entrusted by the national leading group office of biogas construction. Following the successful development of the low-pressure biogas stove of Beijing IV, it was developed in 1982
