4 Yuan Bin Yang Dongming Chong Guoxin Petroleum Company Northwest Petroleum Xinjiang Wuzhu Muqi City No. Wang Ying Wang Jiarong Daqing Temple Design Institute Heilongjiang Province People Qingshan Subject Gas Generator Measured Gas Pre-Separation Compression Pressure Regulating Heating Chengcheng Natural Gas In addition to Civil Fuel Chemicals Outside the raw materials. In towns and areas where natural gas is abundant. Especially in the oil and gas fields where the external power supply is difficult and the gas source is sufficient. The use of ten gas power generation also has a very broad development prospects. Gas generators have a general requirement for fuel gas. The domestic fuel gas generators have a general requirement for fuel gas. The gas volume is determined by the capacity and efficiency of the machine hunger = pressure. The pressure range of the gas supply is related to the type of generator set and the manufacturer. There are two pressure grades with a capacity of 0.30.
6MPa, large capacity unit is 2.33.4 river.
Natural gas does not contain free liquids containing no more than 101 droplets and solid particles.
In order to meet the requirements, the process measures should be based on the requirements of gas generators for the pressure and temperature dew point of the fuel gas containing droplets and solid particles. For the gas generators to supply fuel gas, 7 columns of 1 art measures should be taken. Voltage regulator. It should be determined through technical and economic comparisons whether it is to select a large generator set that is efficient but has to pressurize natural gas, or a small generator set that is relatively inefficient but does not have to press natural gas. According to experience, when the power generation load is greater than 8001, a large generator set with a higher fuel gas pressure is selected. At this time, if the gas source pressure of the natural gas is lower than the minimum intake pressure required by the gas generator set, a boosting facility is required. The compressor outlet pressure should be similar to the pressure range required by the generator set, and the value of natural gas enters the generator set. A rolling facility should be provided. The goal is to keep the fuel gas pressure entering the generator set substantially stable. The pressure regulation is realized by a self-operated pressure regulating valve.
2 Separation and filtration facilities for fuel gas. Separate filtration facilities must be installed for the untreated gas in Shanghai. Separate filtration like a fine filter or a filter separator to achieve it.
The natural gas containing no condensate may not have a pre-separator. For natural gas containing a large amount of liquid, a pre-separator must be provided because the filter filter separator does not allow the free liquid of the natural gas to be smashed.
Heating facility for fuel gas. When the temperature of natural gas can not meet the dew point of the hydrocarbon dew point higher than 5, the fresh-keeping, heat-heating facilities, the natural gas that has passed through the corpse, if its temperature can be guaranteed to be higher than the dew point of the hydrocarbon dew point 5, above, or not The heating of the heating facility can be realized by the heat transfer of other high-temperature mediums of the electric heater. Since the gas-fired power station does not have the high-temperature medium that can be guaranteed by the season, most of the heating methods of the electric heater are adopted, and the construction and purging requirements of the gas supply pipeline are required. In order to ensure the cleanliness of the gas supply pipeline, the gas supply pipe section from the outlet of the filter to the inlet of the gas turbine should be grounded by argon arc welding. In order to reduce the welding, the green section is subjected to sufficient blasting to thoroughly remove the dust and the like which may remain in the welding slag, and the gas turbine 1 must be provided with a filter. In order to filter the debris during the construction and initial production, the typical process of supplying gas to the gas generator set is based on the temperament of the raw material gas, and the gas is supplied to the gas generator set. The raw material gas is treated dry gas and its temperature is greater than the road. When the point and the water dew point are more than 5, the process 1 is used to adjust the gas to a normal filter. The 1 filter is heated into the gas turbine and the raw gas is 42. The condensate in the steam natural gas is greater than 2,413. Pre-separation must be carried out, and the process 2 can be used to adjust the atmosphere. The pre-separation filter separates the heating into the gas turbine inlet or uses the process to adjust the pre-separation filtration to separate the heating gas turbine inlet.
3 The raw material gas is moisture, but when the amount of condensate in the natural gas is less than 20103, the process 2 or such a process can be used to adjust the pressure separation and heat into the gas wheel.
The Shine horizontal feeders are of high volume, high speed component feeding systems that can be capable of feeding a various of sand,rock,and silo materials. Absolutely the capacity of the Horizontal Feeder can be requested by the customers need. They feed components directly from the shipping tubes, or from handling tubes. The tubes are stacked in the feeder horizontally. The components are pushed out of the bottom tube . Automatically eject the empty tube and index the next tube into the feeding position.
