BOILER TYPE SELECTOR
Compare construction and fuel route on one engineering basis.
This comparison is a screening tool, not a final model selection. Confirm steam conditions, load profile, fuel, water quality, emissions, transport and code before manufacture.
| Boiler route | Preliminary capacity | Fuel | Where it is commonly considered | Critical checks |
|---|---|---|---|---|
| WNS fire-tube package | 1–20 t/h | Natural gas, diesel or project-confirmed fuel oil | Compact packaged process-steam duties | Pressure, burner turndown, water treatment, transport and economizer |
| SZS water-tube arrangement | Project-specific | Natural gas or liquid fuel | Larger, variable or project-specific steam duties | Load change, pressure, water chemistry, controls and erection boundary |
| Biomass-fired system | 1–30 t/h | Wood chips, pellets, rice husk and confirmed biomass | Sites with reliable local biomass and suitable handling space | Fuel analysis, storage, feeding, grate, draft, dust and ash systems |
| Coal-fired system | 1–30 t/h | Project-confirmed coal | Markets where coal use and emissions are permitted | Coal analysis, furnace, grate, environmental equipment and local policy |

STEAM BOILER BASICS
What is a steam boiler?
A steam boiler is a pressure system that transfers heat into treated water to generate steam at a specified capacity and pressure. In an industrial plant, the useful system is larger than the boiler body: combustion equipment, water treatment, feedwater, controls, heat recovery, blowdown and condensate return all influence reliability and operating cost.
Selection starts with the real steam-user schedule, required pressure and steam condition. It then checks fuel, feedwater temperature, condensate return, turndown, emissions, transport limits and whether the boiler will ship assembled or be erected at site.
Calculate steam boiler capacity Review the steam-system piping basis
MANUFACTURING & INSPECTION
Verify the factory, project basis and supply boundary.
Review JIELI's workshop processes, pressure-part fabrication and export projects alongside the proposed steam boiler specification. Confirm the design code, inspection records and delivery responsibilities in the quotation.
Direct manufacturing
The Linyi workshop records show plate preparation, forming, welding, heat-transfer assembly and inspection stages. Request the project-specific material traceability and inspection document list when reviewing a steam-boiler proposal.
Traceable project references
Each project reference identifies the destination, capacity, model and stage shown in the photographs, such as workshop loading or installation.
Project code basis
Applicable ASME or CE/PED engineering requirements are reviewed project by project. The proposal identifies the agreed design, inspection and documentation basis.
Complete-system boundary
Water treatment, feedwater, fuel equipment, heat recovery, condensate, controls and site interfaces are coordinated with the boiler rather than left implicit.
SELECTION DATA
Convert process demand into boiler capacity.
Nominal tons per hour alone do not define a stable steam plant. Use the same operating basis when comparing suppliers.
| Input | Why it matters |
|---|---|
| Normal, peak and minimum demand | Determines capacity, turndown, number of units and operating strategy. |
| Steam pressure and condition | Changes useful heat, fuel use, pressure-part design and downstream equipment. |
| Feedwater and condensate return | Feedwater temperature and return percentage affect duty, chemistry and operating cost. |
| Fuel | Natural gas, diesel, oil, biomass and coal require different combustion and auxiliary systems. |
| Water quality | Determines treatment, blowdown and risks of scale, carryover and corrosion. |
| Country and emissions | Local code, altitude, power supply, NOx or particulate limits affect the configuration. |
TPH & CAPACITY GUIDE
Industrial steam boiler capacity from 1 to 20 t/h.
One metric ton per hour (t/h or TPH) equals 1,000 kg/h of nominal steam evaporation. Tonnage alone does not define fuel consumption or usable heat: steam pressure, feedwater temperature, condensate return, blowdown, efficiency and the load profile all change the result.
| Example steam duty | Nominal evaporation | Mass flow | Selection point still required |
|---|---|---|---|
| 1 t/h | 1 t/h | 1,000 kg/h | Pressure, fuel and minimum load |
| 2 t/h | 2 t/h | 2,000 kg/h | Peak demand and burner turndown |
| 4 t/h | 4 t/h | 4,000 kg/h | Feedwater and condensate return |
| 6 t/h | 6 t/h | 6,000 kg/h | Normal versus startup demand |
| 10 t/h | 10 t/h | 10,000 kg/h | Fire-tube or water-tube arrangement |
| 12 t/h WNS project | 12 t/h | 12,000 kg/h | Pressure, burner, code and auxiliaries |
| 20 t/h | 20 t/h | 20,000 kg/h | Fuel analysis, grate, dust and ash scope |
TPH is a starting point, not the complete boiler specification.
A 10 TPH rating means 10,000 kg/h of nominal steam flow; it does not specify fuel use or construction. Compare output at the same pressure and feedwater temperature, then check normal and peak demand, fuel data, emissions limits and supply boundary.
COMPLETE STEAM BOILER SYSTEM
Reliable steam depends on the water, fuel and condensate systems.
A complete steam boiler system may include water treatment, feedwater tank and pumps, boiler, burner or solid-fuel system, economizer, steam header, blowdown, condensate return, chimney, controls and project piping interfaces. The final boundary must be written into the proposal.
Gas supply and combustion
For an industrial gas-fired steam boiler, confirm gas supply pressure and composition, normal and peak steam demand, feedwater conditions and emissions limits before selecting the burner and controls.
Water and condensate
Treatment, deaeration or feedwater heating, condensate return and blowdown affect reliability, efficiency and steam quality.
Controls and operating range
Burner or fuel control, water level, feedwater, pressure, draft, interlocks and alarm logic must support the real load profile.
PROCESS APPLICATIONS
Industrial steam by process and industry.
Industrial steam serves food processing, breweries, textile finishing, pharmaceuticals, chemical processing, paper production, feed mills and laundries. Distinguish direct steam injection from indirect jacket or exchanger heating, then record batch peaks, required steam quality and which condensate streams can be returned.
Food processing steam
Review direct or indirect use, hygiene boundary, peak batch demand and condensate recovery.
Textile industry steam
Map dyeing, washing, finishing and line start-up to normal, minimum and peak steam demand.
Country-specific projects
Fuel availability, water, altitude, electrical supply, emissions, transport and local inspection all matter.

STEAM BOILER FAQ
Answers buyers need before comparing quotations.
These questions connect capacity, construction, fuel and auxiliary scope. Final values remain project-specific and are confirmed against the applicable code and approved design data.
Send Project DataHow should an industrial steam boiler capacity be selected?
Start with normal, peak and minimum steam demand, required pressure, feedwater temperature, condensate return, operating schedule and future expansion. TPH alone is not enough because startup demand, blowdown, distribution loss and burner or fuel-system turndown affect the final selection.
When is a WNS fire-tube boiler different from an SZS water-tube boiler?
A packaged WNS fire-tube boiler is commonly considered for compact gas or oil-fired duties, while an SZS water-tube arrangement may suit larger, more variable or project-specific steam conditions. The final choice depends on pressure, load profile, transport limits, water quality, emissions and the applicable code.
Can one steam boiler operate on both natural gas and fuel oil?
A compatible dual-fuel burner can support natural-gas and fuel-oil operation, but the burner, fuel trains, valves, controls, purge sequence and changeover logic must be engineered together. Fuel pressure, composition and the project safety standard must be confirmed before selection.
What biomass data is required before selecting a biomass steam boiler?
Provide the biomass type, particle size, moisture, ash, lower heating value, bulk density, contaminants and seasonal variation. This information affects storage, feeding, furnace volume, grate, draft, dust collection, ash handling and the reliable steam output.
What is normally included in a complete steam boiler system?
A project scope may include the boiler, burner or solid-fuel equipment, water treatment, feedwater tank and pumps, economizer, blowdown equipment, condensate return, chimney, valves, instruments and control cabinet. The proposal should state every supply and site-work boundary explicitly.
What information should be sent to a steam boiler manufacturer for a proposal?
Send steam capacity and pressure, normal and peak load, fuel data, feedwater temperature, condensate-return rate, operating hours, industry, project country, altitude, electrical supply, emissions limits, code requirements and available boiler-room dimensions.
What is a steam boiler?
A steam boiler transfers heat into treated water to generate steam at a specified capacity and pressure. Reliable industrial operation depends on the complete system: combustion, water treatment, feedwater, controls, heat recovery, blowdown and condensate return.
Can an industrial steam boiler supply steam for direct food contact?
Direct contact and indirect heating require different steam-quality checks. For steam injected into food or used in a hygiene-critical process, specify the required steam grade, permitted water-treatment chemicals and quality at the point of use. Depending on the process standard, filtration or a separate clean-steam generator may be needed. Boiler pressure and evaporation capacity alone do not establish suitability for food contact.
