Sample 1:

The provided diagram illustrates how electricity is generated from coal.

Overall, the process includes several key stages, beginning with coal mining and culminating in power delivery to households and industries, with waste heat being a by-product at various stages.

The first step involves coal being mined at extraction plants. The mined coal subsequently undergoes crushing, breaking it down into finer pieces. These crushed coal fragments are then transported to a gasifier, inside which combustion occurs at elevated temperatures in order to convert the coal into gas.

After this phase is complete, the produced gas proceeds to a separate facility for cooling, with excess heat released as waste. Once cooled, the gas undergoes a cleaning stage whereby any impurities are removed. The purified gas then becomes the input for a gas power plant. Within the power plant, electricity is generated and distributed for domestic and industrial use. It is worth noting that even at this final stage, additional waste heat is still discharged as a by-product.

Sample 2:

The illustration demonstrates the generation of electricity by utilizing a particular type of coal. Overall, there are eight steps in the production, beginning with mining the coal, followed by various processes to the raw material, and ending with distributing the electricity to final uses.

The first five steps involve the conversion of coal into gas, which begins with coal being excavated from a mining plant. After that, it goes through a crushing machine and is delivered by trucks to another factory, where a gasification process transforms the crushed coal into gas. Subsequently, another facility is responsible for lowering the temperature of the gas and releasing the waste heat.

The remaining steps produce electricity. Cool gas is transported to another unit for cleaning and then becomes the input for a gas power plant. While electricity is generated, excessive heat is released as a source of waste. Finally, the electricity produced from the power plant is supplied for both household and industrial uses.

Sample 3:

The diagram illustrates the process of generating electricity from a particular kind of coal.

Overall, this process comprises multiple steps occurring at different facilities: starting from the mining of the coal to the production of gas, and eventually the generation of electrical power used for various purposes.

To begin with, coal is extracted from a mine, after which it is ground down by a crusher. The pulverized coal is then put into a mine cart before being loaded onto a truck for transportation. Once this material has been transported to the factory, it is heated to produce gas.

The process continues with the gas being sent to a separate facility, in which it is cooled while waste heat is discharged. After the cooling process is complete, the gas will be directed to a facility where it is purified. It is thereafter transferred once again to a power plant which uses the gas to generate electricity and expel any excess heat waste. Finally, the electricity produced is distributed via transmission lines to homes and industries.

The drawing demonstrates how electricity is generated from a type of coal.

Overall, it can be seen that there are eight stages included in this procedure, commencing with the extraction of coal and completing with production of electricity. Also, the process takes place at a coal mine and several treatment facilities.

In the initial stage, coal is collected from coal mines. After undergoing a crushing stage, the coal is transported by trucks to a gasifier. This is where high temperatures are introduced, and the pulverized coal is heated and turned into gas, ready for the next steps.

The subsequent stage involves gas being delivered to a cooling plant from the gasifier. Following this, some of this gas is transported to another factory for cleaning, while waste heat is disposed of. After being cleaned, the gas is moved to a power plant to be converted into electricity. Finally, the generated electricity is distributed to households and factories, with waste heat being removed.

The diagram illustrates how to generate electricity from coal.

Overall, the process comprises several stages, starting with the mining and crushing of coal, followed by the heating and cleaning of gas, and culminating in the generation and allocation of electricity.

At the start of the process, coal is extracted from a mine before being transported to a crusher, where it is broken down into smaller pieces in order to burn more efficiently. The coal lumps are then subjected to high temperatures in a gasifier, triggering a combustion reaction as gas and other by-products are produced. Subsequently, the gas is cooled down while the waste heat is released.

The process continues with the gas being cleansed to remove impurities, after which it is pumped into a gas power plant where electricity is generated. During this stage, more waste heat is discharged into the atmosphere. Finally, electricity is distributed to various households and industries.

Sample 6:

The diagram illustrates the various steps involved in the production of electricity from coal.

Overall, the procedure consists of six primary steps, beginning with the extraction of coal from mine and culminating in the distribution of electricity to the grid.

The process initiates at a coal mine, where coal is extracted and then transported to a crusher to be pulverized into small pieces. Following this, the crushed coal is conveyed to gasifiers, where it undergoes heating to transform into gas, followed by a cooling phase. During this phase, the waste heat generated in the gasifier can be later extracted and managed.

Once gasified, the coal-derived gas is cleaned to remove impurities, rendering it suitable for efficient power generation. The purified gas is then directed into a gas power plant where it fuels turbines to produce electricity. Finally, this resulting electricity is distributed to the grid and for consumer use.

Sample 7:

The given picture illustrates how a certain type of coal is used to generate electricity. Overall, there are three main stages in this process. It starts with the extraction of coal, continues with processing this material to generate electricity and culminates with distributing electricity to various locations for household and industrial purposes.

Regarding the material preparation stage, a specific type of coal is mined from coal mines using specialised equipment. It is then ground by crushers and dumped into crates. Finally, the crushed coal is delivered by trucks to thermal power plants.

Concerning the production and delivery stages, the coal received at the plant is first gasified using heat. The gas produced is subsequently pumped into a cooling system where waste heat is released. The following step involves cleaning the gas to remove any impurities before it is utilised to produce electricity in a power plant. At this plant, another volume of waste heat is also released, and the electricity is finally distributed to households for domestic use or to industrial areas.

Sample 8:

The diagram delineates the sequential stages involved in generating electricity from coal.

Overall, the process encompasses six primary stages, commencing with coal extraction from mine and concluding with electricity transmission to the grid.

The procedure starts by excavating coal from mines, followed by transportation to a crusher for pulverization into small fragments. Subsequently, the crushed coal is conveyed to gasifiers, where it undergoes heating to convert into gas before a cooling phase. Throughout this phase, the residual heat generated in the gasifier can be harnessed and managed.

Following gasification, the coal-derived gas goes through purification to eliminate impurities, ensuring optimal efficiency in power generation. The refined gas is then channeled into a gas power plant where it drives turbines to generate electricity. Ultimately, the produced electricity is distributed to the grid and made available for consumer use.

The diagram illustrates the sequential phases involved in harnessing electricity from a specific type of coal.

To commence with, the coal extraction process begins with mining deep underground, followed by crushing to facilitate combustion. Following this initial phase, the crushed coal is transported via lorry to the factory, where it is introduced into a gasifier for combustion, transforming coal into raw syngas. Subsequently, after the syngas undergoes cooling, eliminating excess heat, it undergoes a purification process to remove impurities and pollutants, including carbon dioxide, mercury, and sulfur, ensuring minimal environmental impact. The purified gas is then utilized to drive a gas turbine within a power plant, generating electricity while waste heat is efficiently managed. Ultimately, the electricity generated is distributed across residential and industrial sectors through the national grid.

Overall, the process of generating electricity from coal involves several crucial stages, starting from coal mining and culminating in electricity distribution. This method boasts environmental friendliness by minimizing harmful emissions into the atmosphere.
