300 series coking gas generator set

Coking gas generator set applicable industries:
Coke production enterprises
Coking gas gas overview:
Coking gas, also known as coke oven gas, belongs to high calorific value gas, crude gas or waste gas due to its many combustible components. It refers to a kind of combustible gas produced when coke and tar products are produced after high temperature dry distillation in a coke oven. It is a by-product of the coking industry.
The main components of coking gas:
The main components are H2 (55%~60%) and CH4 (23%~27%), and also contain a small amount of CO (5%~8%), unsaturated hydrocarbons above C2 (2%~4%), CO2 ( 1.5%~3%), O2(0.3%~0.8%)), N2(3%~7%). Among them, hydrogen, methane, carbon monoxide, and unsaturated hydrocarbons above C2 are flammable components, and carbon dioxide, nitrogen, and oxygen are non-flammable components. Among them, unsaturated hydrocarbons above H2, CH4, CO, C2 are combustible components, and CO2, N2, O2 are non-combustible components.
Advantages of 300 series coking gas generator sets:
1. The 300 series gas generator set has the advantages of large cylinder bore, long stroke and large displacement, which can ensure that the output power of the set remains constant.
2. The 300 series unit adopts an internal mixed air intake system and an automatic air-fuel ratio control system, which completely avoids the problem of high hydrogen gas tempering and firing. Prevent backfire and ensure safe gas delivery.
3. Natural suction to ensure the safety of gas transmission. The pressure of the gas source only needs to be greater than 2kpa, which makes the gas unit applicable to a wider range, has a strong applicability to the tar in the gas, and the gas source low-pressure transmission is safer. Self-priming air intake, the gas directly enters the combustion chamber after mixing, no air intake links such as turbocharger and intercooler are required, and there are few components, which naturally reduces the failure rate.
4. The ignition system of the 300 series gas generator sets adopts the ignition system imported from the United States or Germany to ensure controlled ignition, high ignition energy and precise ignition time, so that the work can be more thorough, the energy is larger, and the explosive force is stronger.
5. Removable intake valve box, it is convenient to maintain the intake valve and clean the tar without removing the cylinder head.

If the content of sulfur and ammonia in the combustible gas is high, it will not only seriously corrode the spark plug electrodes, but also increase the acid value in the oil, corrode the internal parts of the unit, and at the same time easily generate deposits, which will increase the wear and corrosion of the engine.
