Selection starts with data
Capacity alone is not enough to select a boiler.
Tell us the operating temperature or steam pressure, load profile, fuel condition, site arrangement and the process being heated. We will use those inputs to shape the equipment and system proposal.
STEAM SYSTEM SELECTION
Coal steam-boiler terminology and selection inputs.
Coal steam boiler and coal-fired steam boiler are common buyer terms for industrial steam systems using project-confirmed coal. Boiler pressure parts, combustion, feeding, draft, dust and ash handling, feedwater, controls and emissions equipment must be engineered as one plant.
Steam profile
Confirm normal, peak and minimum steam demand, pressure, temperature, condensate return and operating schedule.
Coal properties
Provide calorific value, moisture, ash, volatile matter, sulfur, particle size and ash-fusion data for the actual fuel.
Environmental scope
Local particulate, sulfur and other limits affect the dust-control and flue-gas treatment boundary. Final selection must follow the destination-country requirements.
COAL QUALITY AND COMBUSTION
Coal and solid-fuel steam-boiler terminology.
A generic search for a coal boiler or solid fuel boiler does not define steam capacity, pressure, coal properties or the required environmental equipment. For industrial steam service, the boiler, feeding and grate, furnace, fans, dust and ash systems, water treatment and controls must be specified together.
Coal data
Provide calorific value, moisture, ash, volatile matter, sulfur, particle size and ash-fusion behavior for the intended supply range.
Steam demand
Confirm normal, peak and minimum demand, pressure, temperature, condensate return, feedwater and operating schedule.
Emissions boundary
Local particulate, sulfur and other limits determine dust collection, possible flue-gas treatment, fan duty and stack interfaces.

Questions to confirm before technical selection.
These answers provide a preliminary engineering framework. Final configuration depends on the confirmed fuel, duty, site conditions, local requirements and contracted supply boundary.
Open the manufacturer evaluation checklistWhat coal analysis is required before boiler selection?
Provide representative calorific value, moisture, ash, volatile matter, sulfur, particle size and ash-fusion data, with the expected variation. The combustion and emissions system must be based on the actual fuel.
Can the boiler use a different coal after installation?
A different coal may change ignition, heat release, slagging, ash, emissions and capacity. The manufacturer should review the new fuel before operation and confirm any changes to feeding, air distribution or controls.
How should steam capacity and pressure be selected?
Build a time-based demand profile and confirm pressure at each process after distribution losses. Check normal, peak and minimum demand rather than selecting only from connected load.
What dust and ash equipment is needed?
Equipment depends on fuel ash, local particulate and other emissions limits, boiler configuration and site layout. Define dust collection, draft, ash discharge and disposal responsibilities in the project boundary.
What information should be sent for a coal-fired steam boiler proposal?
Send steam demand profile, pressure and temperature, coal analysis, water and condensate data, site conditions, emissions limits, utilities, layout and required equipment, documents and support scope.
