Embodiment Construction

[0031] The incineration plant comprises a combustion chamber 2 with a combustion material inlet 1 through which solid combustion material, such as waste, can be introduced into the combustion chamber 2 . A combustion grate 3 is realized at the bottom of the combustion chamber 2 , by means of which solid and burned material, ie ash, can be conveyed towards the slag outlet 4 .

[0032] Primary air for combustion of solid material is provided from below the combustion grate 3 . The flue gas generated in the combustion chamber 2 is supplied into a vertically extending empty passage 5 . A horizontally extending heat recovery steam generator 6 is arranged downstream of the empty passage 5 .

[0033] The superheater heat exchanger 7 , the evaporator heat exchanger 8 and the economizer heat exchanger 9 are arranged in the heat recovery steam generator 6 , all of which are connected to a common boiler drum 10 .

[0034] exist figure 2 In , nozzles for supplying a gaseous medium suc...

Abstract

The invention relates to an incineration plant for solid material having a combustion material inlet (1) through which solid material can be introduced, a combustion chamber (2) in which the solid material is introduced and in which the solid material is combusted, a combustion grate (3) with which the solid material and combusted solid material can be conveyed through the combustion chamber (2), a primary air supply below the top of the combustion grate (3), at least one nozzle arranged above the combustion grate (3) with which a gaseous medium can be provided, the nozzle having a gas inlet and a gas outlet.

Description

technical field [0001] The present invention relates to an incineration plant for solid material such as waste or biomass, said incineration plant having: a combustion material inlet through which said solid material is introduced; a combustion chamber through which said solid material is introduced into the combustion chamber and the solid material burns in the combustion chamber, thereby generating flue gas; a combustion grate, by means of which the solid material and the burned solid material can be conveyed This passes through the combustion chamber; a primary air supply under the top of the combustion grate; at least one nozzle arranged above the combustion grate, by means of which a gaseous medium, such as secondary air, tertiary air, can be supplied And / or an oxygen-depleted carrier gas, the nozzle has a gas inlet and a gas outlet. Background technique [0002] The incineration plant generally comprises a combustion grate arranged in the lower section of the combusti...
