Design And Fabrication Of An Industrial Gas Cooker
Abstract
Cooker plays an integral role in oil and gas well pads. They generate the heat necessary for separating the oil, gas and water mixture and to keep the gases in their vapor phase during transportation through pipelines. Industrial cooker typically use a portion of the gas coming out of the ground as the fuel to produce the flame for heating. The gases extracted from the ground enter the burner skid (commonly referred to as burner fuel train) at a high pressure and hence they need to be pressure controlled for use in cooker. This work is on fabrication of an industrial gas cooker.

1.0 INTRODUCTION
This work focuses on an industrial gas cooker is a device which is used to generate a flame, in order to heat up products using a gaseous fuel such as acetylene, natural gas, or propane for industrial purpose. Some cookers have an air inlet to mix the fuel gas with air, to enable complete combustion. Acetylene is commonly used in combination with oxygen.
The gas cooker has many applications such as soldering, brazing and welding, the latter using oxygen instead of air for producing a hotter flame, which is required for melting steel. For laboratory uses, a natural-gas fueled Bunsen cooker is used. For melting metals with melting points of up to 1100 °C (such as copper, silver, and gold), a propane cooker with a natural drag of air can be used.
1.1 OBJECTIVE OF THE PROJECT
The objective of this work is to design an industrial device which is used to generate a flame, in order to heat up products using a gaseous fuel such as acetylene, natural gas, or propane.
1.2 HOW COMBUSTION OCCUR IN COOKER
The release of potential energy of fuel by combustion with air requires several
stages, namely.
• Mixing of air and fuel
• Ignition of the mixture
• Chemical reaction
• Disposal of products of combustion from the reaction site so that fresh reactants are available. Except mixing of air and fuel, all other stages are extremely fast such that it is said that if fuel and air are mixed, fuel is burnt. Accordingly mixing is the slowest step in the process of combustion, this can be understood by considering that each mole of carbon theoretically requires 1 mole of oxygen for complete combustion. But 1 mole of oxygen is obtained from 4.76 moles of air. That means 3.76 moles of nitrogen are present with 1 Mole of oxygen. Nitrogen is inert and does not take part in combustion therefore mixing of air+ fuel is important.
1.3 SIGNIFICANCE OF THE PROJECT
An industrial gas cooker is a device which is used to generate a flame, in order to heat up products using a gaseous fuel such as acetylene, natural gas, or propane. Some cooker have an air inlet to mix the fuel gas with air, to enable complete combustion. Acetylene is commonly used in combination with oxygen.
1.4 APPLICATION OF THE PROJECT
The hottest and most efficient of all fuel gases use in gas cooker, acetylene (C2H2) provides high levels of productivity thanks to good localized heating with a minimum of thermal waste. It also requires the least amount of oxygen to ensure complete combustion. This flammable, colourless gas is lighter than air so does not accumulate at low levels, where it could cause a potential hazard. It is generally supplied dissolved in acetone or DMF (dimethylformamide) in specially designed cylinders to prevent decomposition.
A low flame moisture content makes this fuel gas a good choice for many critical heating processes. Typical applications include flame heating, flame gouging, welding, flame hardening, flame cleaning, flame straightening, thermal spraying, spot-heating, brazing, texturing, profile-cutting, branding wooden pallets, wood-ageing and carbon coating.
Acetylene is the only fuel gas recommended for underground working conditions because it is lighter than air. It is also the only fuel gas, for instance, which can be used to weld steel.
In cutting, oxy-acetylene gives the fastest preheating and piercing times of any fuel gas combination.
Benefits include:
• Improved cut quality
• Higher cutting speeds
• Faster cut initiation time
• Reduced oxygen use.
