Natural gas generator is a new environmental friendly gas generator developed to meet the requirements of world environmental protection and the new market environment. Natural gas generators are mainly divided into two types: gas turbine and gas internal combustion generator. The power of gas turbine is relatively large, which is mainly used in large and medium-sized power stations. The power of gas internal combustion generator is relatively small, which is mainly used in small distributed power stations, and the single generator power is 10kw-1000kw.
Natural gas internal combustion power generator is a new type of green environmental protection power to replace fuel oil and coal-fired. Make full use of all kinds of natural gas or harmful gas as fuel, turn waste into treasure, operate safely and conveniently, have high cost-effectiveness, low emission pollution, and are suitable for cogeneration of heat and electricity. The market prospect is very broad.
The world is rich in natural gas resources. Compared with world’s rich natural gas reserves, the proportion of natural gas in world’s primary energy consumption is too small, and it has great potential in the future. In oil fields, gas fields, airports, hotels, hospitals and other fields, more and more natural gas generators are used as essential standby power generation equipment, which can provide reliable power supply during power failure. As long as natural gas is continuously supplied, the generator will generate electricity continuously. Within a few seconds of power failure, as long as the equipment is started, there will be power supply, and the power supply will stop when the switch is turned off – there is no need for users to do any additional work. The equipment is fully insulated and meets the emission standard. It can be predicted that with the increasingly sufficient supply of natural gas and the continuous expansion of the scope of supply, natural gas power generation will have a rapid development in recent years.
What are the requirements of gas generators for gas?
- The natural gas requirements of the gas generator are within 1m before the gas inlet pressure regulating valve ① the natural gas pressure is 100 ~ 300kPa (supercharger) or 50-300kpa (non supercharger); ② The volume content of methane in natural gas shall not be less than 70%; ③H2S≤20mg/Nm3； ④ Impurity particle size ＜ 5 μ m. Impurity content ≤ 30mg/nm3;
If the sulfur and ammonia components in the combustible gas are high, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the engine oil, corrode the internal parts of the unit, and is easy to generate sediment, increasing the corrosion and wear of the engine. - The requirements of gas generator for biogas are within 1m from the gas inlet pressure regulating valve, ① biogas temperature ≤ 40 ℃; ② biogas pressure is 3 ~ 10KPA, and the pressure change rate is ≤ 1kpa/min; ③ The volume content of methane in biogas is not less than 40%, and the change rate is ≤ 2% / min; ④H2S≤200mg/Nm3； ⑤NH3≤20mg/Nm3； ⑥ Particle size of impurities ≤ 5 μ m. Impurity content ≤ 30mg/nm3; ⑦ Moisture content in biogas ≤ 40g/nm3. For biogas with a methane content of 30 ~ 40% by volume, special configuration of the generator is required, and another type of product is selected.
If the sulfur and ammonia components in the combustible gas are high, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the engine oil, corrode the internal parts of the unit, and is easy to generate sediment, increasing the corrosion and wear of the engine. - The gas requirements of the gas generator are within 1m from the gas inlet pressure regulating valve, ① the gas temperature is ≤ 40 ℃; ② Gas pressure 3 ~ 10KPA, pressure change rate ≤ 1kpa/min; ③ The volume content of methane in gas is not less than 9%, and the change rate is ≤ 2% / min; ④ For gas with methane volume content less than 30%, the sum of methane and oxygen volume content shall not be less than 28%, and the oxygen volume content shall not be less than 16%; ⑤ Particle size of impurities ≤ 5 μ m. Impurity content ≤ 30mg/nm3. ⑥ Hydrogen sulfide content is not more than 200mg/m3. For gases beyond the specified range, it is necessary to communicate with the manufacturer and verify whether it is feasible according to the gas composition.
- The requirements of gas generator for coke oven gas are within 1m from the gas inlet pressure regulating valve, ① coke oven gas temperature ≤ 40 ℃; ② The pressure of coke oven gas is 3 ~ 10KPA, and the pressure change rate is ≤ 1kpa/min; ③ Volume content of hydrogen in coke oven gas ≤ 60%; ④H2S≤200mg/Nm3； ⑤NH3≤20mg/Nm3； ⑥ Tar content ≤ 50mg/nm3; ⑦ Particle size of impurities ≤ 5 μ m. Impurity content ≤ 30mg/nm3; ⑧ Water content in coke oven gas ≤ 40g/nm3.
If the sulfur and ammonia components in the combustible gas are high, it will not only seriously corrode the spark plug electrode, but also increase the acid value in the engine oil, corrode the internal parts of the generator set, and is easy to generate sediment, increasing the corrosion and wear of the engine.
