The surface type heat exchanger has tube shell type, sleeve type and other types of heat exchanger. The regenerative heat exchanger is to transfer heat from high temperature fluid to low temperature fluid by means of regenerator composed of solid. The regenerator contacts with high temperature fluid for a certain time, and receives and stores a certain amount of heat, and then contacts with low temperature fluid for a certain time to release heat to low temperature fluid. The regenerative heat exchanger has rotary heat exchanger used in the convection section of the first stage furnace to recover the temperature of flue gas for preheating combustion air; there is also a valve switching type heat exchanger. Fluid connection indirect heat exchanger is a heat exchanger connected by heat carrier circulating in two surface type heat exchangers.
