The invention discloses a circulation utilization system of a coal water slurry industrial-boiler, and belongs to the technical field of circulation utilization of coal water slurry industrial-boilers. The system can preheat coal water slurry by using heat released by water gas cooling. The system includes a gas producer, a flue gas filter, an intercooler and a gas holder, and further includes a water pressure control tank, a first water tank, a second water tank and a controller; the intercooler includes an intercooled heat conducting pipe arranged vertically, the pipe wall of the intercooledheat conducting pipe is internally vertically provided with multiple cold flow vertical-holes, the upper port of each cold flow vertical-hole is formed in the upper surface of the intercooled heat conducting pipe, the lower port of each cold flow vertical-hole is formed in the lower surface of the intercooled heat conducting pipe, and the multiple cold flow vertical-holes are evenly arranged along the circumference of the intercooled heat conducting pipe.
Description
technical field [0001] The invention relates to the technical field of recycling of coal-water slurry industrial boilers, in particular to a recycling system of coal-water slurry industrial boilers. Background technique [0002] When the coal-water slurry industrial boiler needs to generate water gas at a higher temperature after the coal-water slurry enters the boiler, the heating of the coal-water slurry requires heat, but the water gas needs to be cooled before being sent into the gas holder. The generation of water gas requires heating up, and the storage of water gas requires cooling. However, the two temperatures are not mutually utilized at present, resulting in high cost of producing water gas and low energy saving and consumption reduction. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems existing in the existing production of water gas, and provides a method that can preheat the coal-water slurry by using the hea...
