Introduction

The 300 series gas generator sets are widely used in clean energy power generation and comprehensive utilization of waste heat,such as syngas,straw gas, coal gas, natural gas, biogas, blast furnace gas, coke oven gas, blue carbon gas, etc. The rotate speedis mainly at 500r/min and 600r/min,and the power ranges from 400kW to 3000kW. The 300 series gas generator sets use various combustible gas as raw materials for combustion to drive the engine to generate electricity. The engines based on Xichai 300 diesel engine, combined with the advantages of the large cylinder bore and long stroke of 300 diesel engine. The generator sets have ave fully learned from the advanced gas engine technology both at home and aboard. Targeted improvement and R&D have been conducted to meet the requirements of all kinds of combustible gas to ensure the combustion function and reliability of gas engine. In this case, the generator sets can run more smoothly and run for a longer period under full load. Moreover, the interconnection can be more convenient, and the comprehensive efficiency of co-generation can be realized by utilizing waste heat. 300 series gas generator sets can output at high, medium, and low voltage, achieve automatic parallel and grid connected, and have become the most popular exported products among the same power.

Main Technical Features
In practical application, 300 series gas generator sets which is at medium rotate speed, compared with other equipment in China, has obvious advantages:

1. Able to output at high, medium, and low voltage, and reduce initial investment and operating cost
300 series gas generating sets can be customized with output of high, medium and low voltage at 10500V, 6300V and 400V to meet various needs of users. Moreover, the initial investment does not have to include transformers, which can reduce copper losses, contributing to the reduction of operating costs. It not only can be combined to the grids, but can run directly with load,which greatly improves its economic benefit.

2.The stability of output power ensured by the large bore and long stroke
The prime mover of 300 series gas generator sets is remould from 300 series diesel engine with a diameter of 300mm with the characteristics of large cylinder diameter, long stroke, low rotate speed, and large power reserve. It is more suitable for the gas with low pressure than generator sets at high rotate speed, and it is the best prime mover for gas generator sets with stable output power.

3.Long service life ensured by the low rotate speed
The rotate speed is 500r/min and 600r/min. Low rotate speed can reduce the wear of friction pairs of engine parts, increase the service life of the parts,reduce the reserve of spare parts, and improve the economic benefits of users.

4.The normally aspirated non-pressurized generator sets applicable to various gas with low failure rate
The single cylinder of 300 series generator sets has large emissions, with which low-pressure gas and air can be normally aspirated into the prime mover (the pressure of air source should be over than 2kPa), so that the generator sets can be applied to more kinds of gas, and the transmission of low-pressure gas is safer. Moreover, With self-aspirating air intake, mixed gas can enter the combustor directly without air-intake parts like turbocharger and intercooler, so that the failure rate can be reduced.

5.A concise structure and convenient maintenance with simplified layout of straight forward structure of generator sets
300 series gas engine is straight forward engine with large operation space for maintenance, especially the crankshaft upright structure which greatly saves the maintenance time and costs, and can be fixed on site no matter set overhaul or shafting maintenance.

6.Security and high-efficiency of gas ensured by several lines of defense
The advanced air-fuel ratio control technology ensures that the engine is proportional to the ideal mixture. The engine intake pipe is equipped with an explosion-proof valve. Once the temper is automatically released, the flame arrester installed on the pipe quenches the flame to prevent the flame from spreading. The solenoid valve will quickly cut off the gas source to ensure the safety of the genset.

7.Recycling of waste heat and realizing comprehensive utilization of gas-fired cogeneration
The exhaust gas of the genset is directly used in the waste heat boiler to generate hot water or steam. The genset can be cooled by circulating hot water to provide heating bath and other heat. Through comprehensive utilization, the comprehensive heat efficiency of the gas can reach 70%, which improves economic benefits.

8.Online detection and automatic control can be realized by computer monitoring management system
Operation data can be monitored online with monitoring system, and remote management can be realized with functions like automatic grid connect, fault diagnosis, automatic adjustment of air-fuel ratio, etc.
