Image for topic: The diagram below shows how one type of coal is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

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

The image illustrates the process of producing electricity from coal, starting with coal extraction from a mine, which is then transported to a crusher. The crushed coal goes through a series of processes including cooling and cleaning stages where gas and waste heat are generated. The cleaned gas is then channeled to a gasifier where it produces more gas and heat. This gas is subsequently directed to a gas power plant for generating electricity, while waste heat from both the cooling/cleaning and gasifier processes is also utilized in the electricity generation process.

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

The diagram illustrates the process of producing electricity from coal.

Overall, the process includes several stages, beginning with the crushing of coal from a mine and ending with the production of electricity for industries. Coal is turned into gas, then the gas is cooled and cleaned. Some waste heat is also produced during these stages.

Initially, coal is mined and put into a crusher, where it is crushed down into smaller pieces. The crushed coal is then transported by truck to a gasifier. Heat is added to this unit, allowing the coal to be converted into gas.

The gas produced is subsequently sent to a cooling facility. At this stage, some waste heat is released. The cooled gas then undergoes a cleaning process. Once cleaned, it is delivered to a gas power plant, where electricity is generated. Finally, the electricity is supplied to buildings and industrial facilities. The power plant also produces waste heat as a product.

Task Response

The report provides a clear and logical overview of the process, successfully identifying the main stages from coal extraction to electricity distribution. The sequence of events is easy to follow, and the use of cohesive devices helps the flow of information. To improve, ensure that the relationship between the different stages of heat utilization is more explicitly detailed, as the diagram suggests waste heat is integrated back into the generation process rather than just being a byproduct.

Coherence & Cohesion

The report is exceptionally well-organized. The progression from the introduction to the overview and then through the sequential stages of the process is logical and effortless to follow. Cohesive devices such as 'Initially', 'subsequently', 'At this stage', and 'Finally' are used naturally to guide the reader through the stages without being repetitive or intrusive.

Lexical Resource

The vocabulary used is precise, appropriate, and varied. Terms such as 'converted', 'undergoes', 'delivered', and 'industrial facilities' demonstrate a high level of lexical control. The student successfully uses appropriate terminology to describe a technical process, ensuring clarity and professional tone throughout.

Grammatical Range & Accuracy

The report demonstrates a wide range of grammatical structures with full accuracy. The use of the passive voice (e.g., 'is mined', 'is subsequently sent', 'is generated') is particularly effective and appropriate for describing a manufacturing or industrial process. Punctuation is flawless, and there are no errors in sentence structure.
