Abstract

The invention discloses a device for matter heat separation of a solid fuel and fused salt integrated boiler. The device is mainly composed of an expansion groove, fused salt grooves, fused salt guide pipes, an insulating layer, a burning cavity, an air preheating recoverer, an air blower, another air blower, a centrifugal fan, circulation burning pipes, a waste heat recovery water tank, a combustion air cavity, a fuel preheating coil pipe, a high pressure plunger pump, a steam coil pipe, a steam header, a steam generator main body, a high pressure spraying device, a desulfurization and denitrification device, a dedusting lime water pool, a spraying head, a circulation water pump, an induced draft fan, a chimney, a solid matter conveyor, a liquid matter conveyor, a matter decomposing coil pipe, a cyclone separation tower, a decomposing reduction chamber and a cooling tower. The device has the beneficial effects that fused salt of a fused salt constant temperature system is directly heated in a hearth, and the steam pipe temperature and the heat decomposing pipe temperature are controlled by heat of the fused salt; jet fog enters a steam pipe to obtain steam; and materials enter a heat decomposing pipe to conduct matter decomposing. The device further has the beneficial effects that a steam decomposing and separating technology is adopted for replacing an existing decomposing and separating technology, and the problems of complex technological processes, equipment and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of boilers, steam generators and separation and decomposition devices. Specifically, it is a device for thermal separation of solid fuel and molten salt integrated boilers. Background technique [0002] The whole world has been studying how to improve the thermal efficiency of the boiler body to save natural resources. Generally, it is the research on the manufacturing materials and the way of fuel entry, and then gradually produces subcritical, supercritical, and ultra-supercritical. Boiler, but has not broken through the basic structure of the boiler and the way of steam water supply. Currently, it is still in the state of the steam production mode of boiling bubbles, and the fuel combustion, ignition, and waste heat recovery are not ideal, and the investment in the treatment and collection of emissions is huge. , poor effect, etc. [0003] Traditional concentration and drying equipment has complex and m...
