Abstract
A heating apparatus for heating supply of gaseous fluid heats a relatively low temperature gaseous fluid and feeds a heated supply flow to a high temperature gaseous fluid introduction equipment. The heating apparatus has heat exchangers provided with fluid passages through which the low temperature fluid flow passes, a splitting area for dividing a heated supply flow H of gaseous fluid, which is heated by the heat exchanger, into first and second heated gaseous streams H , H , and combustion areas in which a combustion reaction of combustible matter takes place in the existence of the first heated gaseous stream. The heated supply flow or the first stream is introduced into the combustion area and the combustible matter is fed thereto, and the combustion area causes the combustion reaction of combustible matter in the existence of the heated supply flow or the first stream. Hot gas produced by the combustion reaction is exhausted through the heat exchanger. The heat exchanger has a regenerator which accumulates heat in its heat-transferable contact with the hot gas and emits the heat in its heat-transferable contact with the low temperature gaseous fluid. The heating apparatus heats or preheats the low temperature gaseous fluid to a high temperature and feeds the second heated gaseous stream to the equipment.
