Going to Keldagrim for the first time.

The Blast Furnace provides a great opportunity for players to reap great profits by producing a large volume of runite bars (worth 12,368 each), which are coveted by high-level smiths.

Depending on your level of activity, you can produce between 1,500 and 1,600 runite bars in an hour. That means the profit margin falls between 701,625 and 756,725 hourly.

First make sure you are on either world 358, 386, 352 or 387 (the official Blast Furnace worlds). After purchasing the raw materials, deposit 72,000 coins into the coffer. This will allow you to use the furnace without having to worry about operating it. It will remove 1,200 coins every minute automatically for a total of an hour. Then, start by placing runite ore on the conveyor belt first, then emptying your coal bag of coal and depositing that right after. Do three trips of just coal after, and in the third coal trip retrieve your bars from the bar dispenser by clicking on it. Then, do another trip of runite ore and coal, and immediately retrieve a second inventory of bars. Repeat this process from the beginning until you either run out of ore, or the coffer is empty.
