针对炼化尾气气源，专门研制了利用该气源的发电机组。针对燃气易回火和爆震的特点，采用了至新的进气方式、排气方式和空燃比控制方式，进行了至新的设计并经过耐久性试验。机组从安全性和利用效率两方面解决了多年来对此类燃气利用的难题，广泛应用于焦炉煤气、高炉煤气、兰炭气、煤气化气、电石气、化工驰放气等领域，开创了可燃炼化尾气利用的新市场。
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.
按照尾气中主要可燃成分区分，可分为两种:一种以焦化尾气为代表，其气体中氢气含量较高的(含氢气高于30%，且其它可燃成分低于氢气)，可选用高氢燃气机组发电利用;一种是氢含量较少(含氢气低于30%，且其它可燃成分高于氢气)，可选用低氢燃气机组发电利用。
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.

气隔离技术
Gas isolation technology
朵用燃气和空气隔离的进气技术，空气经增压器压气后进入左、右进气管，燃气由各缸燃气阀独立供气。空气和燃气在进入发动机缸内后混合，在进气管内没有空气和燃气的混合燃气，防止进气管的回火放炮，保证了进气系统的运行安全。
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.
纯空气扫气技术
Pure air scavenging technology
朵用纯空气对燃烧室扫气的技术，避免了未燃烧的混合燃气进入排气管，防止排气管爆燃放炮，保证排气系统、增压器的运行安全;同时， 由于只有空气而没有燃气扫气，减少了燃气的损失，提高了燃气发电的利用效率。
The technology of using pure air to sweep the combustion chamber prevents unburned mixed gas from entering the exhaust pipe, prevents the exhaust pipe from exploding and blasting, and ensures the safe operation of the exhaust system and turbocharger; At the same time, because there is only air but no gas scavenging, the loss of gas is reduced and the utilization efficiency of Gas-fired power plant is improved.
自动控制空燃比技术
Automatic control of air fuel ratio technology
自动控制空燃比，确保机组运行在合理的空燃比范围， 保障机组稳定运行，减少人工的干预，同时提高了发动机的燃烧做功效率。
Automatically control the air fuel ratio to ensure that the unit operates within the most reasonable range of air fuel ratio, ensuring stable operation of the unit, reducing manual intervention, and improving the combustion efficiency of the engine.
电站厂房设计方面
In terms of power plant building design
发电机房安装轴流风机强制通风，防止有毒气体和可燃气体在机房内积聚;发电机房内配置可燃气体、有毒气体报警装置，与机房轴流风机联动，报警后触发轴流风机启动进行强制通风，保证机房内可燃气体、有毒气体含量处于较低状态.
Install axial flow fans for forced ventilation in the generator room to prevent the accumulation of toxic and combustible gases in the room; The generator room is equipped with combustible and toxic gas alarm devices, which are linked with the axial flow fan in the machine room. After the alarm, the axial flow fan is triggered to start for forced ventilation, ensuring that the content of combustible and toxic gases in the machine room is low
