Burner inserter/infobox

The Burner inserter is the most basic and slowest type of Inserter. They are powered by burning Fuel, compared to the more advanced inserters which are powered by electricity. When moving fuel, they will fuell themselves as well, which machkes it useful for filling Boilers with coal. This has the advantage that they will continue working even if the power fails. This is not the case for electrically powered inserters. While having no drain, they consume vastly more energy than comparable Inserters when active.

Burner inserters cannot grab moving items from either red belts or blue belts. They also cannot grab moving items from turning belts if the item's on the far side. They however will try to grab things, and consume fuel in their attempts. Eventually, the Burner Inserter will run out of fuel, be unable to refuel itself, and stops working.

Even though they don't use electricity, Burner inserters can be linked to and manipulated by the logistic and the circuit network.

For more information on mechanics and uses see Inserters.

Power Comparison

A burner inserter consumes (at a rate of 188kW) exactly 1 coal (8.0MJ burner energy) every 42.55 seconds (0.0235 coal/second) when running continuously. In practice, the burner inserter may not run continuously, however burner inserters consume no idle power, therefore 1 coal will last 42.55 seconds of run time. In this time, a burner inserter will transfer items approximately 25 times. In contrast, a regular inserter will transfer approximately 256 times using the same amount of coal (through steam power). However, due to the electric energy drain of other inserters, a burner inserter is more coal efficient than a regular inserter if the inserter only operates less than once every 1560 seconds (26 minutes). This makes these burners useful in situations where a boiler-fueled electrical plant is switched off for large amounts of time, acting as a backup power plant. These burners are also useful for automatical recovery from a blackout after fuel starvation of a power plant, since they don't require power to resupply the boilers to get power production going again.
