To establish the project design basis for “Waste Heat Boilers — WHB”, confirm “Waste-heat source and steam generation” and its inputs: Define hot-gas source, composition/flow, recoverable-temperature basis, fouling/corrosion and required steam pressure/temperature. Final values, supply limits and acceptance criteria are recorded in approved engineering documents; no generic capacity or catalogue guarantee is assumed.
From project definition to delivery
Engineering of Waste Heat Boilers — WHB concentrates on gas and steam temperature profiles, pinch and approach temperatures, steam conditions, circulation, gas-side pressure drop, water chemistry, metallurgy, fouling and start-up transients. The selected configuration is verified against normal, minimum, start-up, shutdown and credible upset cases, then checked for operability, maintainability, energy use, process safety and site interfaces before the design is frozen.
The design basis for Waste Heat Boilers — WHB is defined from service data, design conditions, and battery limits. For this equipment, Waste-heat source and steam generation and Feed and thermal conditions must be completed in the datasheet and design documents; performance values and guarantees are set only after the project basis is approved.
Materials, corrosion allowance, sour-service requirements, piping classes, nozzle design, insulation, coating, supports and maintenance access are coordinated with the actual process conditions and project code hierarchy.
Control philosophy, alarms and trips, cause-and-effect logic, interlocks, start-up and shutdown sequences, safe depressurization and operator access are developed consistently from the P&IDs through functional testing.
Battery limits, tie-in points, structural loads, cabling, instrumentation, drains, vents, access routes, lifting envelopes and shipping constraints are controlled through coordinated models and interface drawings.
From project definition to delivery
Proposal quality depends on complete input data and an explicit acceptance basis. The following lists provide a practical starting point and are completed during technical clarification.
Technical Datasheet
This is a published high-pressure water-tube WHB family for hot combustion flue gas. It is a product/sector reference—not a universal WHB range or a project guarantee.
| Parameter | Published value | Reference basis | Applicability / limit |
|---|---|---|---|
| Superheated-steam power | 30–90 MW | Published range for a high-pressure waste-heat steam-boiler product family. | The cited range is associated with energy/biomass exhaust-gas service; available heat and steam conditions govern. |
| Steam pressure | 40–90 bar(g) | Published steam-pressure span for the same WHB family. | Pressure is not a stand-alone rating; steam flow, temperature, circulation, materials and pressure-boundary code must be designed together. |
| Hot-flue-gas temperature reference | 450–550 °C | Published inlet-temperature range in the cited energy-recovery application. | Source gas composition, fouling, ash/alkali, corrosion and allowable outlet temperature may change the surface arrangement and duty. |
