Change of Operation Parameters of Waste Incinerator by Formation of Deposits

Abstract:

This article is focused on formation of unwanted deposits in the municipal waste incinerator and their influence on incinerator operation. The solid deposits build up on heat transfer surfaces in flue gas channel of waste incinerator. The power stations fired solid fuels sometimes can have problems with growing of deposits. On this point of view, the municipal waste incinerators are a special category, because the municipal waste contains a lot of different types of compounds. Formation of deposits on heat transfer surfaces has in generally bad influence on operating parameters of waste incinerator. Deposits decrease the heat transfer from the flue gas into the working fluid and thereby it reduces the efficiency of incineration facility. The effect of decreasing of heat transfer ability was investigated on large-scale waste incinerator in Brno, where were monitored changes of operating parameters before and after the planned shutdown of the device. Deposits can too affect the shape of flue gas channel and thereby reduce his size. It can have more negative impact on waste incinerator operation.
