Choose a circulating fluidized bed (CFB) boiler supplier by evaluating the complete project fit—not just the quoted boiler price. Start with your required steam or heat output, fuel characteristics, operating conditions, emissions requirements, site constraints, and delivery scope. Then compare suppliers on engineering capability, documentation, quality controls, commissioning support, and long-term service. At Genjux, we recommend using the same written specification and evaluation criteria for every bidder so that proposals can be compared on an equivalent basis.

A supplier can only propose a suitable CFB boiler when the project requirements are sufficiently clear. Prepare a process description covering the required steam or hot-water duty, operating schedule, load variation, and planned fuel supply. If the boiler will serve an existing plant, provide available utility data and explain how the new equipment must connect to current systems.
State the required output, pressure, temperature, and whether the duty is continuous, seasonal, or variable. Use a consistent basis for comparing offers, such as the same steam condition and feedwater assumptions. For example, “100 tonnes per hour at 10 MPa” can be a useful illustrative project input, but it is not a default CFB boiler specification; your process and engineering team must define the actual requirements.
Also describe expected turndown, start-up frequency, backup arrangements, and future capacity needs. These details affect the proposed configuration and auxiliary systems, so omitting them can create gaps between the quotation and the operating plant. Ask each supplier to identify the conditions under which its stated output and performance are expected to apply.
Provide fuel analysis where available, including the expected range of heating value, moisture, ash, sulfur, and particle size. If you plan to use more than one fuel, explain the blend and the expected frequency of switching. A moisture figure such as 25% may be included as an illustrative case for comparison, but the supplier needs your actual fuel data and its variability to assess the design.
Share site elevation, ambient conditions, available plot space, transport access, water quality, and relevant local environmental requirements. Provide a preliminary plot plan if possible, including stack location and connection points. Missing site information can affect layout, foundations, auxiliary equipment, and installation planning.
Review each proposal against the same technical schedule rather than relying on marketing descriptions. The offer should make clear what is included in the boiler package and what is supplied by others. Request a list of design assumptions, battery limits, interfaces, and exclusions so that you can identify scope differences early.
Confirm how the supplier addresses the furnace, solids circulation, fuel feeding, heat recovery, flue-gas cleaning, ash handling, fans, controls, and other project-specific systems. The exact package varies by design and contract scope, so do not assume that a component is included unless the offer says so. Ask for a process flow diagram, equipment list, preliminary layout, and responsibility matrix where appropriate.
Review the proposed fuel range and ask how deviations from the supplied fuel analysis may affect operation or performance. CFB combustion is generally associated with a relatively moderate combustion temperature; designs commonly operate in the approximate range of 800–900°C, although the actual value depends on the design and operating conditions. Treat any temperature or emissions value in a proposal as a project-specific commitment only when its definition, measurement basis, and verification method are stated.
Ask suppliers to define the performance values they are prepared to guarantee, the test conditions, and the measurement procedures. Clarify how fuel quality, ambient conditions, equipment availability, and operating practice affect those guarantees. A number without stated assumptions is difficult to compare and may not describe performance under your site conditions.
Request a proposed commissioning and acceptance plan, including the documents, operating inputs, and responsibilities needed for testing. Check whether the plan addresses the boiler’s intended load range and the fuels included in the contract. If a requirement is important to project economics or compliance, make sure it appears clearly in the technical and commercial documents rather than only in discussions.
Genjux supply professional and honest service.
A boiler project depends on coordinated engineering, manufacturing, delivery, installation interfaces, and post-sale support. Evaluate whether the supplier can explain who will be responsible at each stage and how technical questions will be managed. Ask for relevant project references or comparable experience where available, and verify that the examples match your fuel, capacity range, and project scope rather than relying on broad claims.
Ask what inspection and quality records will be provided for the equipment covered by the contract. Confirm the applicable codes and regulatory requirements with your engineering team, then ask the supplier to state how its proposed design and documentation address them. Do not assume a certificate, approval, or compliance status unless it is specifically identified and applicable to your project and jurisdiction.
Discuss the project schedule in terms of design submissions, approval cycles, manufacturing milestones, inspections, shipment, installation support, and commissioning. Ask which schedule assumptions depend on timely buyer decisions or information. A realistic milestone plan is more useful than an unqualified delivery promise because it exposes dependencies and helps both parties plan around them.
Clarify the support available during installation, commissioning, troubleshooting, and operator familiarization. Ask how spare-parts recommendations are developed and how technical queries are handled after handover. These details help you assess whether the supplier’s support model fits your location, maintenance resources, and operating schedule.
At Genjux, we encourage project buyers to share their technical specifications, fuel information, site conditions, and target schedule before comparing proposals. This allows us to discuss the proposed scope and identify information that may still be needed for a project-specific quotation. The final responsibilities, deliverables, and service arrangements should be confirmed in the agreed contract documents.
Compare the total proposed scope, not simply the equipment price. Check whether engineering, auxiliary equipment, controls, documentation, inspection, packing, freight, installation supervision, commissioning, and training are included or excluded. Differences in these items can make two headline prices unsuitable for direct comparison.
Review payment terms, quotation validity, delivery basis, warranty wording, and any conditions that affect price or schedule. Record unresolved technical points as commercial clarifications, since an assumption that remains open can lead to change requests later. For each offer, maintain a written list of inclusions, exclusions, buyer responsibilities, and pending decisions.
Use a documented scoring process, but do not let a single weighted score replace technical review. A lower-cost offer may not represent equivalent scope, while a detailed offer may still need clarification on fuel limits or performance testing. Record the reasoning behind the final selection so that procurement, engineering, and operations teams share the same understanding.
The right circulating fluidized bed boiler supplier is the one whose documented design, scope, performance basis, project plan, and support model fit your industrial requirements. Define the duty and fuel envelope first, compare complete proposals against common criteria, and resolve technical and commercial assumptions before contract award. This approach helps your team identify genuine differences between offers and reduce avoidable scope ambiguity.
Your next step is to prepare a project data package with operating requirements, fuel analysis, site information, applicable regulations, and target schedule. Share it with shortlisted suppliers and request a written response that identifies assumptions, exclusions, and open questions. Genjux welcomes project inquiries from industrial buyers seeking to discuss CFB boiler requirements and evaluate a project-specific supply scope.
