What Information is Required to Select a 7.5 MW Coal Boiler?

A 7.5 MW coal boiler can be used in an industrial heating system, a hot water network or another process that requires a defined heat output. However, capacity alone is not sufficient to determine the boiler model. The customer must first confirm whether the required 7.5 MW coal boiler is a hot water boiler, thermal oil boiler or another type of heating equipment.

If the project requires hot water, the outlet temperature, return temperature and system pressure must be provided. If the 7.5 MW coal boiler is intended for a specific production process, ZOZEN also needs the operating temperature, daily working hours and load variation.

Coal analysis is a necessary part of boiler selection. The calorific value, moisture, ash content, volatile matter, sulfur content and particle size influence the combustion system. These values help determine the furnace arrangement, fuel feeding method, air distribution and flue gas treatment equipment for the 7.5 MW coal boiler.

The project location also affects the design. Local emission limits, ambient temperature, altitude, power supply and water quality should be included in the technical questionnaire. Without these details, a supplier can provide only a preliminary configuration rather than a defined quotation for the 7.5 MW coal boiler.

A complete system may include the boiler body, coal feeding equipment, slag removal system, fans, circulation pumps, water treatment equipment, control cabinet, dust collector and chimney. The supply boundary of the 7.5 MW coal boiler should state whether civil works, installation materials and site commissioning are included.

ZOZEN manufactures coal-fired steam boilers, coal-fired thermal oil boilers and circulating fluidized bed boiler systems. Since the enquiry does not specify the heat-transfer medium or operating pressure, ZOZEN should complete the technical selection before assigning a model to the 7.5 MW coal boiler.

ZOZEN has over 30 years of industrial boiler manufacturing experience. Its production site covers 150,000 square metres and is equipped with specialised production lines for boiler drums, membrane walls, coils and other components.

For a commercial proposal, the customer should submit the application, medium, temperature, pressure, coal analysis and emission requirements. ZOZEN can then prepare the configuration and auxiliary equipment list for the 7.5 MW coal boiler.
