A generator set has been specially developed to utilize the refining tail gas source. In response to the characteristics of gas being prone to backfire and detonation, a new intake method, exhaust method, and air fuel ratio control method have been adopted, and a new design has been carried out and durability tests have been conducted. The unit has solved the problem of using such gas for many years in terms of safety and utilization efficiency. It is widely used in coke oven gas, blast furnace gas, semi coke gas, Coal gasification gas, calcium carbide gas, chemical purge gas and other fields, creating a new market for the use of combustible refining tail gas.
按照尾氣中主要可燃成分區(qū)分,可分為兩種:一種以焦化尾氣為代表,其氣體中氫氣含量較高的(含氫氣高于30%,且其它可燃成分低于氫氣),可選用高氫燃?xì)鈾C(jī)組發(fā)電利用;一種是氫含量較少(含氫氣低于30%,且其它可燃成分高于氫氣),可選用低氫燃?xì)鈾C(jī)組發(fā)電利用。
According to the main combustible components in tail gas, it can be divided into two types: one is represented by coking tail gas, which has a high hydrogen content in the gas (containing more than 30% hydrogen, and other combustible components are lower than hydrogen). High hydrogen gas units can be selected for power generation and utilization; One is that the hydrogen content is relatively low (containing less than 30% hydrogen, and other combustible components are higher than hydrogen), and low hydrogen gas units can be selected for power generation and utilization.

Duo uses gas and air isolation intake technology, where air is compressed by the turbocharger and enters the left and right intake pipes. The gas is supplied independently by the gas valves of each cylinder. After entering the engine cylinder, air and gas are mixed, and there is no mixed gas of air and gas in the intake pipe to prevent backfire and explosion in the intake pipe, ensuring the safe operation of the intake system.
