Abstract
A method of carrying out a gas combustion process with recovery of the heat from the combustion gases, which comprises passing said gases during the stationary condition of the process through a recuperator in which a part of the heat released is used for heating the air required for the combustion, and then passing the gases through a reformer in which a part of the residual heat is used for converting fresh gas to be burned with steam, in which method at least during the non-stationary conditions of the process a cooling medium is supplied to the combustion gases before introducing them into the reforming reactor.
Claims4
A method of carrying out a gas combustion process having stationary and non-stationary conditions in a combustion chamber to which gas and air are supplied wherein heat from flue gas generated during the combustion process is recovered, comprising the steps of:
- extracting heat from the flue gas by passing the flue gas through a recuperator;
- heating the air supplied to the combustion chamber with the extracted heat;
- extracting further heat from the flue gas by passing the flue gas through a reformer;
- converting in said reformer, with said further extracted heat, a combustible gas and steam into a resulting gas to be supplied to the combustion chamber for use in combustion;
- and
- supplying, during non-stationary conditions of the combustion process, a cooling medium to the flue gas before passing the flue gas through said reformer.
