New: KALPA CAD, our CAD program that works natively in DWG and DXF
FireCAD

Thermal design software for industrial steam boilers

Design the boiler before you build it.

FireCAD sizes the furnace, boiler bank, superheater, economizer and air heater for solid-fuel, oil and gas-fired steam boilers. Boiler manufacturers and consultants in more than 30 countries have used it since 2002.

Software that follows the flue gas, from furnace to stack

Each program covers one kind of equipment. They share the same fuel and flue-gas database, the same units and the same report layout, so a design moves from one to the next without retyping.

One range, from 200 kg/hr to 1000 TPH

Fire tube boiler
200 kg/hr to 50 TPH
Water tube package boiler
3 to 150 TPH

How a design run works

  1. Enter the duty

    Steam flow, pressure and temperature, feedwater temperature, fuel and excess air. Units in MKS, SI or FPS.

  2. Let AutoDesign size it

    AutoDesign proposes a first layout from the duty, so you start from a sensible design and not from a blank sheet.

  3. Refine each surface

    Gas temperatures, heat duty and heating surface are listed for the furnace and every convection surface. Change the layout and run again.

  4. Print the report

    A detailed report for the customer, the inspector or your own file.

Follow the heat through the boiler

FireCAD lists gas temperature, heat duty and heating surface for the furnace and every convection surface.

Cutaway of a grate-fired water-tube boilerFlue gas leaves the furnace at about 1050 degrees Celsius, passes the superheater, the boiler bank, the economizer and the air heater, and reaches the stack at about 150 degrees Celsius.
