Abstract

anticorrosivo para a caldeira. a presente invenção refere-se à caldeira anticorrosiva, que contêm composto de amina, representado pela fórmula (1): (em que cada um de m e n é um número inteiro de 1 a 3), ou contém um eliminador de oxigênio e o composto de amina, representado pela fórmula (1). o anticorrosivo é, de modo geral, empregado em uma caldeira operada com um superaquecedor ou uma turbina de vapor, ou numa caldeira em que a água tratada é alimentada, e pode, mais eficazmente, manter o ph da água da caldeira, além de poder prevenir a corrosão, não apenas do tanque da caldeira, mas também do sistema inteiro da caldeira, incluindo um sistema condensado de alimentação, sem a adição de uma grande quantidade de sal de fosfato ou elevando a relação em mole de na/po~ 4~ a 3 ou maior.
