Abstract

Patente de Invenção: "PROCESSO PARA OPERAçãO DE UMGERADOR DE VAPOR E GERADOR DE VAPOR PARAEXECUçãO DO PROCESSO". Para obtenção de uma eficiênciaparticularmente alta, sob supressão de ensujamento eescorificação na operação contínua de um gerador de vapor (1),com uma potência de vapor, que compreende uma câmara decombustão (8) e um superaquecedor (12), que apresenta váriassuperfícies de aquecimento (18), bem como uma chaminé (30), noqual a câmara de combustão (8), o superaquecedor (12) e achaminé (30) são atravessados por uma corrente de gás defumaça, de acordo com a invenção, a temperatura do gás defumaça (T1), que atua sobre as primeiras, vistas na direção decorrente da corrente de gás de fumaça, superfícies deaquecimento (18), é ajustada de tal modo que a temperatura deamolecimento para partículas de cinzas contidas na corrente degás de fumaça não é atingida e à câmara de combustão (8) éalimentado ar fresco (F), com uma temperatura de ar fresco (T2)reduzida em pelo menos T2 = 15K.Invention Patent: "PROCESS FOR THE OPERATION OF A STEAM GENERATOR AND STEAM GENERATOR TO PERFORM THE PROCESS". To obtain a particularly high efficiency, under suppression of clogging and scoring in the continuous operation of a steam generator (1), with a steam power, comprising a combustion chamber (8) and a superheater (12), which presents several heating surfaces (18), as well as a chimney (30), in which the combustion chamber (8), the superheater (12) and the chimney (30) are crossed by a stream of smoke gas, according to the invention, the gas temperature smoke (T1), which acts on the first ones, seen in the direction arising from the smoke gas stream, heating surfaces (18), is adjusted in such a way that the cooling temperature for ash particles contained in the smoke gas stream is not reached and to the combustion chamber (8) fresh air (F) is fed, with a fresh air temperature (T2) reduced by at least T2 = 15K.
