Boiler economisers

Transfer heat from flue gas to feedwater, make-up water or another suitable sink.

Start with site dataOpen the assessment tools
01

What the measure changes

Transfer heat from flue gas to feedwater, make-up water or another suitable sink.

02

Evidence required

Fuel, firing profile, stack temperature, oxygen, dew point, sink temperature, flow, fouling condition and materials.

Inzonex removable modular insulation on industrial equipment
Equipment heat loss

Measure exposed hot surfaces

Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.

  • Design target: surface temperature at or below 45 °C, subject to the application and design review
  • Claimed heat-loss reduction: up to 96%, subject to the measured boundary and insulation specification
  • Removable construction for inspection and maintenance access
  • Calculation record available for the selected equipment and operating conditions

Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.

03

Constraints and risks

Condensation, corrosion, fouling and insufficient heat-sink demand must be assessed.

04

Possible applications

Sector membership does not establish feasibility. Confirm the actual process duty.
