石油炼化、煤化工、电石生产过程中产生的大量炼化尾气，氢气含量往往高达60%以上。这种气体成分复杂、热值低、易燃易爆，传统内燃机根本无法“驾驭”——回火放炮是家常便饭。炼化尾气发电机组，正是通过一系列专有防爆技术，成为高氢尾气的“驯火者”，将曾经只能排空放散的“危险分子”驯服为稳定输出的电能。

The large amount of refining tail gas generated in the processes of petroleum refining, coal chemical industry, and calcium carbide production often has a hydrogen content of over 60%. This gas has a complex composition, low calorific value, and is flammable and explosive, making it impossible for traditional internal combustion engines to "handle" - tempering and firing are commonplace. The refining tail gas generator set, through a series of proprietary explosion-proof technologies, has become the "tamer" of high hydrogen tail gas, taming the "dangerous molecules" that could only be discharged into stable output of electricity.

一、使用范围：锁定高氢炼化尾气

1、 Scope of use: Lock high hydrogen refining tail gas

炼化尾气发电机组适用场景覆盖石油炼化、煤化工、电石生产、兰炭生产等行业。具体尾气类型包括：焦炉煤气（含氢55-60%）、电石尾气、兰炭气、甲醇驰放气、化工裂解气等。

The applicable scenarios of the refining tail gas generator set cover industries such as petroleum refining, coal chemical industry, calcium carbide production, and blue carbon production. The specific types of exhaust gases include coke oven gas (containing 55-60% hydrogen), calcium carbide exhaust gas, blue charcoal gas, methanol purge gas, chemical cracking gas, etc.

根据尾气中氢气含量可分为两类：高氢型（氢气含量高于30%，非常高可达100%）选用高氢燃气机组；低氢型（氢气含量低于30%）选用低氢机型。机组单机功率可达500-700kW，转速600-1000r/min。

According to the hydrogen content in the exhaust gas, it can be divided into two categories: high hydrogen type (hydrogen content higher than 30%, up to 100%) uses high hydrogen gas turbine units; Low hydrogen type (hydrogen content less than 30%) should be selected. The single unit power of the unit can reach 500-700kW, with a speed of 600-1000r/min.

二、核心优势：本质安全与技术创新

2、 Core advantages: intrinsic safety and technological innovation

进气隔离技术——杜绝回火：这是炼化尾气发电机组非常核心的安全创新。采用燃气和空气隔离的进气方式——空气经增压器进入进气管，燃气由各缸燃气阀独立供气，空气和燃气在进入气缸后才混合燃烧。进气管内没有预混合燃气，从根源上防止了回火放炮。

Air intake isolation technology - preventing backfire: This is the core safety innovation of the refining tail gas generator set. The intake method adopts gas and air isolation - air enters the intake pipe through the supercharger, and gas is independently supplied by the gas valves of each cylinder. The air and gas are mixed and burned after entering the cylinder. There is no premixed gas in the intake pipe, which prevents backfire from the root cause.

纯空气扫气技术——防止排气管爆燃：采用纯空气对燃烧室扫气，避免了未燃混合燃气进入排气管，防止排气管爆燃。同时，由于只有空气扫气而无燃气损失，提高了燃料利用效率。

Pure air scavenging technology - preventing exhaust pipe explosion: Pure air is used to sweep the combustion chamber, avoiding unburned mixed gas from entering the exhaust pipe and preventing exhaust pipe explosion. Meanwhile, due to only air scavenging without gas loss, fuel utilization efficiency has been improved.

抗爆震与智能控制：采用大能量点火系统、降低压缩比、中冷技术和空燃比自动控制，抑制高氢燃料的爆震倾向。自动化程度高，可实现远程监控和孤岛运行，减少人工干预。

Anti knock and intelligent control: adopting high-energy ignition system, reducing compression ratio, intercooler technology, and automatic control of air-fuel ratio to suppress the tendency of high hydrogen fuel to knock. High degree of automation, capable of remote monitoring and islanding operation, reducing manual intervention.

在双碳目标下，炼化尾气发电机组通过将原本排空的废气转化为电能，大幅降低企业碳排放强度，同时节约外购电费、创造发电收益，实现环保与经济效益的双赢。

Under the dual carbon goal, the refining tail gas generator unit significantly reduces the carbon emission intensity of enterprises by converting the originally discharged exhaust gas into electricity, while saving external electricity costs and creating power generation revenue, achieving a win-win situation of environmental protection and economic benefits.
