DEVICE FOR BURNING SUSPENSION FUELS Russian patent published in 2023 - IPC F23C6/00 

FIELD: energy.

SUBSTANCE: device for burning suspension fuels contains a combustion chamber, which has the shape of a parallelepiped with a square horizontal section, on the front wall of which fuel pneumatic nozzles are mounted, and blow nozzles are installed on the side and rear walls, an ash catcher made in the form of a funnel is installed in the lower part of the chamber, an ash and slag removal chamber in the form of a cylinder with a diameter greater than the diameter of the ash catcher funnel neck by 2 times or more is installed below ash collector, with an open lower end immersed in water, filling a bath with one inclined wall installed below, above the bottom and inclined wall of which an ash and slag removal scraper conveyor is mounted, while the ash and slag removal chamber is connected to the combustion chamber by a pipeline with a built-in fan, and a chamber for afterburning fuel and cooling flue gases, made in the form of two or more sections with shielded walls located in series one after the other. An additional combustion chamber is installed between the combustion chamber and the chamber for afterburning the fuel and cooling the flue gases.

EFFECT: increased efficiency of CWF combustion by ensuring the stability of the ash melting temperature in the furnace, low underburning coefficient and controllability of the boiler performance.
