FAQ: How To Build A Gas Blacksmith Forge?

Can you run a forge on natural gas?

Natural gas forges run well, and are the industrial standard. It is far more economical than propane, and will produce enough heat to melt steel. They don’t run on atmospheric burners (venturi) beyond very small flames, because the gas pressure is too low.

What is the best fuel for a forge?

Coal and propane are the most typical fuels used in blacksmith forges. On the East Coast, coal is readily available and therefore more affordable than on the West Coast. Coal burns more efficiently and hotter than wood. Because of its efficiency, the volume of coal needed is substantially less, too.

What gas does a forge use?

A gas forge typically uses propane or natural gas as the fuel.

How hot can a propane forge get?

The combustion temperature of propane is 1,967 degrees F for combustion with air and 2,526 degrees for combustion with pure oxygen (The Engineering ToolBox). Typical forge welding temperatures for a propane forge are accepted as 2,300 degrees F, and common forging can be accomplished at a lower temperature.

Can you use natural gas?

Most U.S. natural gas use is for heating and generating electricity, but some consuming sectors have other uses for natural gas. The industrial sector uses natural gas as a fuel for process heating, in combined heat and power systems, and as a raw material (feedstock) to produce chemicals, fertilizer, and hydrogen.

Can you forge steel with a wood fire?

With a regular wood fire you won’t be able to get the steel hot enough, probably no more than 900 degrees. you can use the wood to make charcaol if lack of coal is the problem.

Is a coal or propane forge better?

Propane is very easily obtained and has the advantage of being portable, cleaner, and hotter than coal and charcoal. Most small forges will need a single propane torch to work metal, but may need to have two burners to properly forge weld.

What burns hotter charcoal or coal?

Coal is not very easy to light up, but after lighting, it burns for a longer time and burns hotter than charcoal. Charcoal is natural to light up but doesn’t burn as hot as coal. It also does not burn for a longer time. But coal is very efficient in producing a high amount of heat.

Can you use charcoal in a forge?

Charcoal has much more carbon than normal wood (hence the black color) and is a much more efficient fuel source for a blacksmith forge. Charcoal will burn longer and hotter than normal wood and is comparable with coal as a fuel source – more on coal later. Charcoal was the fuel of choice for centuries of blacksmithing.

How hot is a charcoal forge?

More or less air will decrease the temperature. This means that the maximum temperature of a coal fire in a forge is about 3,500°F (1′927°C).

How hot is a blacksmith forge?

Blacksmith forges can reach 3,500℉ (1,977℃) if you’re using a coal forge. However, the temperature varies based on the fuel, type of forge, and metal you work with. Not all forge welding projects require such a high temperature, nor does all types of fuel reach this heat.
