To prepare an accurate quotation for an industrial steam boiler, a manufacturer needs more than the required boiler capacity.
At minimum, provide:
The more complete the project data, the easier it is for the manufacturer to select the correct boiler and provide a quotation that reflects the actual project scope.
If you do not yet have a complete technical specification, start with five essential parameters:
Capacity + Working Pressure + Fuel + Operating Hours + Installation Country
These five parameters allow a boiler supplier to make an initial assessment.
For final boiler selection and a detailed quotation, however, additional process and site information is normally required.
Specify the required output of the boiler.
For a steam boiler, capacity may be expressed in:
If possible, provide three values:
For example, simply requesting a “10 t/h steam boiler” does not show whether the plant continuously consumes 10 t/h or normally operates at a much lower load with only short production peaks.
A real load profile helps the manufacturer evaluate boiler sizing, burner turndown and whether one boiler or multiple boilers may be more suitable.
For steam boiler quotations, specify the pressure required by the process.
Useful information includes:
The boiler should not automatically be selected at the highest available pressure.
The required process condition should be defined first.
Most process-heating applications use saturated steam, while certain industrial or power applications may require superheated steam.
Tell the manufacturer:
If you are unsure, describe the actual process application instead of guessing a steam temperature.
Specify the available fuel at the installation site.
Common options include:
If natural gas is available at the project site, buyers can review suitable gas-fired steam boiler configurations and burner requirements before requesting a quotation.
Where a consistent solid-fuel supply is available, biomass-fired steam boilers require more detailed fuel information, particularly moisture, calorific value, ash content and particle size.
For projects considering electrification, electric steam boilers should be evaluated together with available grid capacity, voltage and electricity tariffs.
For gas projects, useful information can include fuel composition, heating value and available supply pressure where known.
For biomass projects, provide as much fuel information as possible, including:
Fuel information affects the burner or combustion system, fuel-handling equipment, emissions solution and expected operating cost.
Provide:
A boiler operating continuously has very different lifecycle requirements from one operating only a few hours per day.
Operating hours are also necessary when comparing annual fuel consumption, industrial steam boiler efficiency under real operating conditions, and total cost of ownership.
For steam boiler projects, provide available information about:
If a recent water-analysis report is available, send it with the RFQ.
Water conditions can influence the required treatment system, blowdown strategy, reliability and long-term boiler performance.
Water quality should also be evaluated together with the boiler’s heat-transfer surfaces, feedwater system and other steam boiler components.
Tell the supplier whether condensate from the process will be returned.
If possible, provide:
Condensate return affects the boiler’s water and heat balance and should be considered when evaluating the complete steam system.
Do not only state the boiler size.
Tell the manufacturer what the steam will actually be used for.
Examples include:
Process information helps engineers understand load behavior, steam requirements and operating priorities.
Always provide the country—and preferably the region—where the boiler will be installed.
This is important because requirements can vary by location, including:
For export projects, the destination market should therefore be confirmed before the final boiler configuration is selected.
If the project has defined emissions limits, include them in the RFQ.
Depending on the project and fuel, relevant requirements may involve:
Do not assume that one emissions specification applies worldwide.
The applicable requirement should come from the installation market and project permit conditions.
For example, U.S. projects may be subject to applicable EPA requirements for industrial, commercial and institutional boilers, depending on the facility, boiler and fuel category.
Tell the manufacturer about any required codes, standards or certifications.
Depending on the project and destination market, pressure-equipment requirements may involve standards such as the ASME Boiler and Pressure Vessel Code (BPVC) or other market-specific requirements.
Depending on the destination and project, this may include requirements related to:
If your project requires a specific certification, ask the supplier to confirm that the quoted equipment is actually covered by the relevant scope.
Useful site information can include:
Site limitations can affect boiler configuration and auxiliary-equipment selection.
Specify whether you require only the boiler or a more complete boiler system.
Depending on the project, the quotation may need to include different types of boiler auxiliary equipment, such as:
Always ask for a clear list of inclusions and exclusions.
A low boiler price can be misleading when major auxiliary equipment is excluded.
Tell the supplier what level of control and monitoring is expected.
Requirements may include:
The term “automatic boiler” alone is not sufficiently specific for a detailed project quotation.
A complete RFQ should also specify commercial requirements where known.
These may include:
This helps prevent a quotation for boiler equipment alone from being compared against another supplier’s complete installed-system scope.
Before requesting a quotation, prepare as many of the following items as possible:
| RFQ Information | What to Provide |
|---|---|
| Boiler type | Steam / hot water / other |
| Capacity | Minimum / normal / peak |
| Working pressure | Required process pressure |
| Steam temperature | Saturated / superheated |
| Fuel | Type and specification |
| Operating hours | Hours/day and days/year |
| Application | Industry and process |
| Feedwater temperature | °C or °F |
| Water quality | Analysis report if available |
| Condensate return | Flow/percentage and temperature |
| Installation country | Country and region |
| Site altitude | If relevant |
| Emissions | Applicable local limits |
| Certification | Project-specific requirements |
| Electricity | Voltage/frequency/capacity |
| Automation | PLC/HMI/SCADA/remote |
| Auxiliary equipment | Required system scope |
| Site restrictions | Space/access/transport |
| Delivery | Required schedule |
| Installation/commissioning | Required or not |
Yes.
You do not need to know every engineering parameter before contacting a boiler manufacturer.
If your project is still at an early stage, start with:
Required capacity + working pressure + fuel + application + operating hours + installation country
Then provide any available information about water, emissions, certification and site conditions.
A competent engineering team can identify which additional data is required before final boiler selection.
If you are still comparing capacity, pressure, fuel options and lifecycle costs, read our complete Industrial Steam Boiler Buying Guide before preparing the final RFQ.
At minimum, a boiler manufacturer normally needs the required capacity, working pressure, fuel, application, operating hours and installation country. Feedwater, condensate return, emissions, certification and site information allow a more accurate engineering quotation.
You may receive a preliminary price, but capacity alone is usually insufficient for a reliable project quotation. Pressure, fuel, steam conditions, auxiliary equipment, certification and installation requirements can materially change the equipment scope.Buyers who are still evaluating lifecycle economics can also review how equipment scope, operating conditions and efficiency affect the total project cost in the Industrial Steam Boiler Buying Guide.
The installation country helps determine applicable emissions, certification, electrical, documentation and project requirements. Export boiler specifications should therefore be matched to the destination market.
Not always for an initial quotation. However, water-quality information becomes important when selecting water treatment, blowdown strategy and related equipment. If a water-analysis report is available, include it with the RFQ.
Yes. Minimum, normal and peak demand provide a better basis for boiler sizing than nameplate capacity alone. They also help evaluate burner turndown, part-load operation and multi-boiler configurations.
Yes, if you need a complete steam system. Clearly state whether the quotation should include items such as the burner, economizer, feedwater system, water treatment, controls, chimney and emissions equipment.
Provide the manufacturer with your capacity, working pressure, fuel, operating hours, application and installation country first. Then add feedwater conditions, emissions limits, certification requirements and required auxiliary equipment where available.
