Our system will evaluate the answer based on this AI-generated description.

The image shows a coal-based energy production process flowchart with connections: coal to crusher (no numerical data), crusher to gasifier (no numerical data), gasifier produces gas and heat, gas to cooling (produces waste heat), cooling to cleaning (no numerical data), cleaning to gas power plant (produces waste heat), gas power plant outputs electricity. No numerical data points/percentages are provided in the image.

Given the complexity of the image, the above description may not be entirely accurate.

The diagram demonstrates the production of electricity from one type of coal. It includes crushing the coal, cooling and cleaning in the process.

Firstly, coal obtained from the factory is crushed into smaller pieces. The crushed pieces are later carried to gasifier to produce gas. Heat is produced along with the gas in this stage. However, the excess heat will not aid the process. The cooling stage is essential for the produced gas, and the heat is also resulted as waste.

Cleaning the gas is also critical in the production of electricity. Ultimately, the purified gas is later used to obtain electricity at the gas power plant. Heat is also discharged as waste along with electricity. There are plenty of applications for electricity, such as in factories and buildings.

In summary, there are five main stages in the production, heat is resulted in three stages. Among them, cooling stage and the final stage produce heat as waste.
