Known Parameters for the Boiler Test Object

Barrel shape Boiler Heat Loss Test Object

Before starting the simple modelling I think it is worth looking at the known parameters for the boiler test object. From these there will be some simple assumptions and estimations. Assumptions Lumped point mass. Single temperature measurement represents the temperature of the object. Heat capacity does not change with temperature. Local air temperature represents ambient … Read more

Thermal Conductivity of Wood

thermal insulation of a boiler

In model making and engineering we use wood as a thermal barrier, hence it is good to understand the thermal conductivity of wood. A typical example is in the insulation of a boiler. The thermal conductivity of wood is affected by: density moisture content grain direction structural irregularities temperature Density Plotting the thermal conductivity across … Read more

Boiler Heat Loss Test Object

boiler heat loss test object

My original boiler heat loss test object was a round disc of mild steel and copper. However, this doesn’t relate that well to the actual boiler. This is so that I can test different types of boiler insulation and multi-layer insulation. My original idea for measuring the thermal insulation for the boiler was to make a … Read more
