Abstract

MÉTODO DE DETECÇÃO ONLINE DE CONCENTRAÇÃO DE METAL ALCALINO GASOSO EM CHAMA DE QUEIMA DE CALDEIRA. Trata-se de um método de detecção online de concentração de metal alcalino gasoso em chama de queima de caldeira. O método inclui selecionar a linha espectral característica de usuário a ser medida; com base na linha espectral característica do metal alcalino, construir um modelo de ajuste entre a resistência à radiação da linha espectral característica do metal alcalino na chama de queima e a concentração de metal alcalino gasoso e a temperatura da chama; calibrar o espectrógrafo sob a resistência à radiação absoluta; medir um objeto de chama que corresponde a uma concentração de metal alcalino pelo espectrógrafo calibrado a fim de obter a resistência à radiação e a temperatura da chama da linha espectral característica do metal alcalino. O método de detecção pode detectar a concentração do metal alcalino gasoso na chama de queima do forno de detecção rápida e precisamente, bem como detectar o teor dos metais básicos, envolve dispositivos simples, baixo custo e é adequado para a medição de campo.
