The invention provides a
system for increasing the garbage incinerator
steam temperature through percolate
marsh gas. The
marsh gas generated by percolate is reasonably utilized, the utilization rateof the
marsh gas is increased, the situation that the
marsh gas is sprayed into an incinerator to incinerate, and the local high temperature is caused is avoided, and safety influences on boiler equipment due to the flammable and combustible characters of the
marsh gas are avoided as well. The high-temperature
smoke generated due to
marsh gas incineration is used for heating overheat steam of thegarbage incinerator, garbage
incineration power
plant steam parameters are further improved, and efficient power generation is achieved. Components of
smoke generated through marsh gas
incineration are simple, the situation of high-temperature
corrosion is avoided, and equipment cost and expense increasing caused for improving steam parameters of a conventional garbage incinerator is reduced; andwaste heat of the high-temperature
smoke generated due to marsh gas
combustion is utilized for heating primary air, the problem about low-temperature
corrosion of an
air preheater is solved, meanwhile, the
steam turbine steam extraction volume, for heating the primary air, of a garbage incineration
waste heat boiler is reduced, and the steam volume for power generation is increased.
