Honeycomb coal can bring warmth to everyone in winter. Once upon a time, every household in the northern rural areas would pile up a lot of honeycomb coal and store it in order to spend this cold winter warmly. However, with the development of science and technology, honeycomb briquette not only wastes resources but also pollutes the environment, and is gradually eliminated. However, the unused honeycomb briquette is not useless, but it still has a great effect!

First, give it to people in rural areas or mountainous areas.

Now the development speed of the city is far beyond everyone's imagination. Honeycomb coal has long been invisible in many places, but this does not mean that natural gas and gas have been developed in all parts of China. There are still many poor places in our country, and they are still cooking by burning firewood. They need honeycomb coal, which is ground into powder, mixed with clay in a certain proportion, and then pressed into briquettes by machines. Although it increases the cost, for some rural areas, rural areas are second, and there are many other functions in the process of honeycomb coal combustion.

The fine ash after combustion can be used as raw materials for cement production by electrostatic precipitator, and the coarse slag can be used as building materials by slag ship. In addition, honeycomb cinder can improve the fertility of red soil, because honeycomb cinder is alkaline and red soil is acidic, and the combination of them will greatly improve soil fertility. Nitrogen oxides in flue gas are denitrated to produce nitrogen and water, and sulfide is desulfurized to produce gypsum, which also has many functions. Many institutions will buy gypsum, which is also an economic source. Finally, most of the water discharged through the chimney is steam, and even greenhouse gases can be treated with carbon dioxide collection devices in the future.
