Estimate the consumption of acetylene (DA) and oxygen per meter of cutting a 10mm thick plate

 To estimate the consumption of acetylene (DA) and oxygen per meter of cutting a 10mm thick plate using oxyacetylene cutting, we need to consider several factors:

1. Cutting Speed: The cutting speed determines the amount of time the torch is in operation per meter of cutting.

2. Gas Flow Rates: The flow rates of acetylene and oxygen determine the consumption of these gases per unit time.

3. Efficiency: The efficiency of the cutting process affects the actual gas consumption.

4. Plate Dimensions: The dimensions of the plate being cut also influence the total gas consumption.

Typically, the consumption rates of acetylene and oxygen are provided in terms of cubic meters per hour (m³/hr) for a given cutting thickness and cutting speed.

For a 10mm thick plate, assuming a moderate cutting speed and efficiency, and using typical consumption rates:

• Acetylene (DA) consumption: Approximately 0.3 to 0.5 cubic meters per hour per millimeter of cutting thickness.
• Oxygen consumption: Approximately 1.5 to 2.5 cubic meters per hour per millimeter of cutting thickness.

Let's calculate the consumption for a 10mm plate per meter of cutting:

1. Acetylene (DA) consumption:

   • Assuming a moderate consumption rate of 0.4 m³/hr/mm.
   • Consumption for cutting a 10mm plate: 0.4 m³/hr/mm * 10mm = 4 m³/hr
   • To convert to cubic meters per meter of cutting, we divide by 60 (minutes) since 1 hour = 60 minutes: 4 m³/hr / 60 = 0.067 m³/meter

2. Oxygen consumption:

   • Assuming a moderate consumption rate of 2 m³/hr/mm.
   • Consumption for cutting a 10mm plate: 2 m³/hr/mm * 10mm = 20 m³/hr
   • To convert to cubic meters per meter of cutting, we divide by 60: 20 m³/hr / 60 = 0.33 m³/meter

So, approximately 0.067 cubic meters of acetylene (DA) and 0.33 cubic meters of oxygen will be consumed per meter of cutting a 10mm thick plate using oxyacetylene cutting. Keep in mind that actual consumption rates may vary based on specific conditions and equipment settings. It's advisable to consult the equipment manufacturer's recommendations for precise consumption rates.
