Abstract

MéTODO PARA CONTROLAR O VALOR DE GáS CALORìFICO E DISPOSITIVO DE CONTROLE DE VALOR CALORìFICO E DISPOSITIVO DE CONTROLE DE VALOR CALORìFICO DE GáS. Apresenta um método de controle do valor calorífico do gás que é capaz de suprimir uma flutuação do valor calorífico de um gás combustível e fornecer o gás combus:ível como um gás combustível estabilizado; o mécodo de concrole do valor calorífico do gás inclui as ecapas de: suprimlr uma flutuação do valor calorífico de um gás combustível a ser fornecido a um sistema de combustão (2) ao sujeitar o gás combustível a uma mistura temporizada dentro de um tanque (5) formado com uma entrada de gás (6) e uma samda de gás (7) separadamente; medir uma flutuação do valor caor::ico do gás combustível rendo sido então suprimida; e diminuir ou aumentar uma caloria do gás combustível em uma localização a jusante do tanque (5) , de modo que a flutuação do valor calorífico então medida fique dentro de uma faixa de flutuação permrssrvel para que o gás combustível torne-se utilizável no sistema de combustão (2).METHOD FOR CONTROL OF CALORIFIC GAS VALUE AND CALORIFIC VALUE CONTROL DEVICE AND CALORIFIC GAS VALUE CONTROL DEVICE. It presents a method of controlling the calorific value of gas which is capable of suppressing a fluctuation of the calorific value of a combustible gas and providing the combustible gas as a stabilized combustible gas; the concrete calorific value method of gas includes the steps of: suppressing a fluctuation of the calorific value of a combustible gas to be supplied to a combustion system (2) by subjecting the combustible gas to a timed mixture within a tank (5 ) formed with a gas inlet (6) and a gas probe (7) separately; measuring a fluctuation of the chaoric value of the combustible gas then being suppressed; and decreasing or increasing a calorie of the combustible gas at a downstream location of the tank (5), so that the calorific value fluctuation then measured is within an permeable fluctuation range for the combustible gas to become usable in the system. combustion (2).
