Abstract

The invention provides a coal gasification fine slag granulation and blending combustion system. The system includes a mixing and stirring machine, granulation equipment and anhydration equipment. Themixing and stirring machine stirs and mixes coal gasification slag and a binder; the granulation equipment granulates the stirred and mixed coal gasification slag and binder to form particles; and the anhydration equipment dries the particles and transports the dried particles to a boiler for blending combustion, wherein the binder includes starch, amide and bentonite. According to the invention,when the blending combustion is carried out on the coal gasification fine slag granulation, the coal gasification fine slag granulation particles can be fully burned in the boiler by stirring and mixing the coal gasification fine slag granulation and binder and then granulating. The stability of the combustion of the coal gasification fine slag granulation particles can be ensured by angydratingthe particles formed by the granulation. the coal gasification fine slag can be ensured to form the clean particles with sufficient strength and the blending combustion cost can be ensured to be lessthan the combustion economic value by selecting the components of the binder, which facilitates the promotion of the blending combustion system.

Description

technical field [0001] The invention belongs to the field of waste treatment, in particular to a coal gasification fine slag granulation blending combustion system. Background technique [0002] Coal gasification fine slag refers to the ash left after the coal is completely gasified in the gasifier in the coal chemical industry. It is a kind of industrial waste. With the development of my country's coal chemical industry, especially the rapid development of the new coal chemical industry With the development, the output of coal gasification fine slag is also increasing year by year. At present, the annual output of coal gasification fine slag in my country has exceeded 30 million tons. If such a large amount of coal gasification fine slag is not disposed of in time and allowed to be piled up in the open air, it will cause serious pollution to the atmosphere and soil. In addition, coal gasification fine slag has a relatively high residual carbon content, which can generally r...
