Application of gas station in generation

Using GCC technology to optimize the producer gas generator system
The producer gas generator adopted technology, widespread efficiency not high question, investigate its reason, is mainly because the energy is not complete. Therefore, we can use less technology to mature, the producer gas generator technology to further improveimprove the efficiency of power generation.
IGCC is the "gas-steam combined cycle power generation technology," from coal gas purification, gas turbine, and steam generator is composed of three parts. less technology is the use of fuel energy and heat energy power generation, including gas power and steam generation in two stages. The phase, of combustion gas, is the use of kinetic energy, the expansion of the gas burning after the second stage, recovery of high-temperature fuel gas burning power generation after the exclusion of, the production of steam power generation. is the use of thermal energy. At present, the producer gas generator system uses only the stage of loss or second stage, supplemented by the lack of power stage, becomes an lGcc small power stations, power generation efficiency is improved obviously
As far as logic is concerned, the gasifier, gas turbine, and steam power generation equipment form without a fixed choice, according to the power station installed capacity, investment in areas such as Europe and the United States, Japan, and now Chinese but powerplants in large scale, generally in the 250lW above, in the selection of the gas stove., it cannot choose the production of smaller atmospheric fixed bed coal gasifier, because of the need to select hundreds of furnace, so the general choice of pure oxygen gasification and for 30MW the following power station, considering the gasification furnace capacity and investment issues, the atmospheric fixed bedgas producer is the choice.
For example, an hour generating capacity of 10Mw furnace gas power station needs to set the 500-kilowatt gas intemnal combustion generator sets 18 sets, each generator can be discharged fue gas 500-600 'c 12000m3/h, the production of steam for steam turbine power generation, every hour can power generation 2-3Mw. Using GCC technology, the efficiency of generating a furnace gas power generation system is 1.2 -1.3 times the original.
