Features of DC-driven drilling rigs:
1.High efficiency: Heat efficiency is about 32% - 40%; The CHP System efficiency can even reach 80%. And the genset uses few water and power itself.
2.Broad scope: The fuel can be coal mine gas (with firedamp content over 5%), high hydrogen content, low heat (over 900kcal), low pressure gas (over 300mmH2O).
3.Rated power range: It can run single or run in grid.
4.Advanced technology: The inflammation technology is our factory's patent, and the genset can be controlled with computer. The key spare part such as timing part, sparkle part, adjusting pressure valve etc. are the advanced products in the world. The generator are produced according to Siemens Technical certificate.
5.Small dimension and weight, easy to install and deliver.
6.Fast on and off. Easy operation and maintenance.
7.It takes little time to build the power station (about one month to build a power station).
8.Safety: The genset has several protection safeguards; In grid, it has self protection function.
9.We can supply the relatied systems, such as coal mine gas send-off system, methane handling system etc., and these systems are both inexpensive and advanced.

Installation requirements:
1.The requirement of the set to gas pipe and lubricating oil:
The outside of the pipe connecting with set should be clean, free, in order and the pipes shoud be strictly airproofed to avoid leaking of oil, water, and gas.
2.The requirement while installing gas pipe:
On the pipe, there should be making-pressure-steady equipment dehydrating equipment, check valve and Pressure gauge to control the pressure before gas entering the measuring pressure valve. After installation, it should be checked carefully again before running.
3.Installation of in & out system:
There must be single exhausting pipe with muffler. While designing muffler and pipe, workers should pay more attention to it to avoid water and other feculence back to cylinder.
4.Lubricate system:
The oil used by the set should be stored in clean can. And it should be sufficient deposition and sieved before being used.
