The method of heating water, a combination of pressurized fire tube HRSG

Waste heat boiler and heating pressurization method water, fire tube combination. Now run the unit fouling seriously affect the operation cycle. In the chemical industry systems, high temperature flue gas waste heat generated by the positive pressure, under current technical conditions, reliable gas purification method is still cold wet cleaning. Thus reducing the gas temperature, a large sensible heat recovery is an important means comprising energy conversion efficiency. Because of this particularity crude gas, the sensible heat recovery system is complex, for recovering waste heat of the high pressure yet more mature experience. The present invention includes : bearing housing ( 1 ), in the the upper pressure housing / with a lower pressure intake / outlet conduit, in said the upper bearing housing is provided and introduced into the lead pipe joint fittings, the pressure within said housing halves boiler fire tube structure; a lower pressure inside the housing is a water-tube boiler structure, said bearing an upper housing connected to the pressure system of the riser, the riser and the downcomer system of the system are connected to the drum ( 8 ). The present invention is for pressurized waste heat boiler.
