cast iron piston and aluminium conrod


April 14, 2021 Nigel 0

The piston is a cylindrical part which reciprocates in the cylinder bore of an engine and transmits the force of the gas pressure through the connecting rod to the crankshaft. This means the piston needs [more…]

Maximum Boiler Insulation

April 14, 2021 Nigel 0

What does maximum boiler insulation look like? When I say “look” I mean in terms of heat loss as this is then something to aim at in terms of design. How much insulation is required? [more…]

Electrically Heating the Boiler

April 12, 2021 Nigel 0

Electrically heating the boiler will allow me to correlate the mathematical model of the boiler. This will also allow me to explore boiler insulation techniques. The instrumentation of the small vertical boiler has allowed me [more…]

flame interaction with the boiler

Flame to Boiler Distance

April 9, 2021 Nigel 0

One thing that has concerned me is what is the optimal Flame to Boiler Distance? The original firebox and methylated spirit burner was generating approximately 54W. At the operating point of the boiler at 40psi [more…]

A Model of the Model Boiler

April 7, 2021 Nigel 0

So, I’m building a Model of the Model Boiler. The model is a mathematical model and to be honest it is in the simplest terms. The boiler is the small vertical one made as a [more…]

boiler cooling curve

Cooling Curve

April 6, 2021 Nigel 0

When measuring any thermal properties of an object, one of the first things to measure is the cooling curve. This will help to establish a number of factors. This is also a good curve to [more…]

Boiler Instrumentation for Testing

April 5, 2021 Nigel 0

In order that I can understand why the boiler is not quite working as expected I first need to setup boiler instrumentation for testing. The instrumentation is all around temperature measurements. For this setup I’m using: [more…]

Spirit Fired Boiler

April 3, 2021 Nigel 0

My intention with the miniature traction engine is to use a spirit fired boiler. When I say spirits I mean methylated spirits. This is a clean and simple way to fire a boiler. The tank [more…]

Electrolysis of Water

March 30, 2021 Nigel 0

A look at the electrolysis of water. This is the process for the electrochemical decomposition of water in a divided electrolytic cell by electrolysis. Electrolysis is the process of changing the chemical structure of a [more…]
