SYSTEM FOR NATURAL GAS PREPARATION FOR COMBUSTION IN BOILERS

摘要

FIELD: power industry.;SUBSTANCE: invention can be used in gas-using industrial enterprises, including thermal power plants (TPPs). The system for natural gas preparing for combustion in boilers contains a high pressure gas pipeline the first output of which is connected to the input of a throttle, which is connected to a low pressure gas pipeline connected to a natural gas consumer. The second output of the high pressure gas pipeline is connected to the first input of the regenerative heat exchanger, the first output of which is connected to the separator, and the second output is connected to the low pressure gas line. The first output of the separator is connected to an expander kinematically connected to an electric generator. The output of the expander is connected to the input of another separator, the first output of which is connected to the pump. The pump output is connected to the first input of the liquefied gas (LG) storage, the second input of which is connected to the second output of the separator. The LG storage output is connected to the second pump connected to a gasifier connected to a low pressure gas pipeline. The second output of the other separator is connected to the second input of the regenerative heat exchanger, which is connected to the low pressure gas pipeline by its second output.;EFFECT: expansion of the system application niche due to the possibility of using gases of any composition, regardless of the high-boiling fractions weight ratio.;1 dwg
