Coal-to-Gas Power Generation Project

 

Gas gas overview:

Coal gas is a gas containing combustible components obtained by processing coal as raw material. According to the processing method, gas properties and uses, it is divided into: water gas, semi-water gas, air gas (or producer gas).

 

Main components of gas:

The main components are H2 (7%~15%), CO (23%~31%), CH4 (1.5%~3%), N2 (46%~54%), CO2 (3%~8%) A small amount of H2S, O2.

 

Advantages of 300 Series Gas Generator Sets:

1. The 300 series gas generator set has the advantages of large cylinder bore, long stroke and large displacement, and is suitable for low calorific value gas, which can ensure the continuous and constant output power of the set.

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. Naturally inhaled 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.

6. The low speed ensures the service life of the unit, the annual operation is guaranteed to be 8000h, and the overhaul period is 60000h.

7. The unit can be connected to the grid manually or automatically, or it can operate in an island, which can realize functions such as remote monitoring and operation.
