How many litres of furnace oil an hour does a Nagaur forging unit burn?

The Nagaur profile's 1,200,000 litres a year over 41 forging units is about 29,270 litres each. With forging units working 6 hours a day for 23 to 25 days a month, my estimate is 16 to 18 litres per working hour, or 98 to 106 litres a day. Test it against your own invoices.

What the profile says about the working day

• Forging units operate for 6 hours a day, 8 am to 2 pm; machining units for 8 hours, 8 am to 4 pm.
• Units operate 23 to 25 days in a month.
• Production depends on the number of hammers installed and market demand.
• Oil fired furnaces are used in the forging units. Furnace oil is 1,200,000 litres a year for the cluster, and 41 of the 55 units are forging units.

The division

1,200,000 litres over 41 forging units is about 29,270 litres a unit a year, as on the live Nagaur furnace oil page. If a unit works 23 to 25 days in all twelve months, that is 276 to 300 days and 1,656 to 1,800 forging hours. The result is 16.3 to 17.7 litres per forging hour, or 98 to 106 litres per working day.

This is my estimate. The profile does not say units work every month, nor that the oil is all burnt in the six forging hours.

Why your number will differ

• Oil may also be burnt outside the 8 am to 2 pm window while a furnace is brought up to temperature before the hammers start.
• Drop hammer units make full forging pliers and hammers over 750 grams; spring hammer units mostly make half forging pliers and lighter hammers.
• The profile calls the furnaces locally made of clay brick and mud with poor insulation and no monitoring, so expect a wide spread from unit to unit (my reading).

Check it on your invoices

1. Add the litres bought in a month and adjust for stock at month end.
2. Divide by the days the furnace was lit.
3. Compare with 98 to 106 litres a day. A figure far above it points at a furnace to look at first.

The arithmetic (estimate)

• Per unit: 1,200,000 / 41 = 29,270 litres a year
• Days: 23 x 12 = 276 and 25 x 12 = 300; hours at 6 a day: 1,656 and 1,800
• Per hour: 29,270 / 1,800 = 16.3 and 29,270 / 1,656 = 17.7 litres
• Per day: 29,270 / 300 = 98 and 29,270 / 276 = 106 litres

Litres, unit count and working pattern are the profile's own. The twelve month assumption is mine.

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so you have the litres bought each month to divide by the days you lit the furnace. It is not a third-party verifier and does not issue credits.
