### Piston

April 14, 2021

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

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

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…]

### Optimising the Firebox and Burner

April 9, 2021

This won’t be the last, but optimising the firebox and burner has moved the boiler to a place where it can deliver steam to a steam engine. This has involved a number of changes to [more…]

### Flame to Boiler Distance

April 9, 2021

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

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…]

### Cooling Curve

April 6, 2021

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

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

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

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…]
