Abstract

"CALDEIRA DE GáS DE EXAUSTãO AUTO REGULáVEL". A invenção refere-se a uma caldeira de calor perdido (1) com rendimento variável, funcionando com circulação natural. O cilindro de vapor/água (2) funciona como um tanque de armazenagem de vapor (7) e de água de alimentação (8). Todo o gás de exaustão (52) flui através da parte de convecção (41), em que dessa forma as superfícies de transferência térmica são automaticamente submetidas a uma limpeza devido à elevada velocidade de fluxo. A produção de vapor (7) é controlada através de alteração do nível (48) de água e da quantidade da mesma na parte de convecção (41). A base do controle é constituída pelas diferentes características de transferência térmica do líquido e do vapor. O cilindro de vapor/água (2) é ligado à extremidade inferior da parte de convecção (41) por intermédio do tubo de dreno (19), onde são dispostas válvulas (20) que controlam o nível (48) da água, que podem ser ou continuamente ajustáveis, ou do tipo aberto/fechado. Um circuito de controle separado controla o nível de água de alimentação no cilindro de vapor/água (2). Diferentes arranjos de tubo de alimentação (6) e antepara (47) aquecem a água de alimentação (8) e condensam o vapor (7).
