My sister in laws new stove blackens her pots and pans on medium heatcan anybody tell me what causes it?

Question

She uses butane.

Answer 1

Poor burning of the gas. There is something wrong with the stove and she should get it checked out asap. If the gas is burning poorly, it will put out more CO2 and can cause health issues.

Is it a clean blue flame or is it orangish? You want light light blue to where it's almost clear.

Answer 2

Ain't nothing to do but adjust the orifice on each burner with a 7/16th wrench. a nut is located on the burner valves just before the air shutter on the base of each burner you turn the adjustment nut and lower the flame. If she is using a newer model stove that is a natural gas model with what you call sealed burners then nothing can be done by adjustment. New parts must be bought and replaced on each burner, oven too
open hole burners can run on propane or natural but the stove must be set up for butane by flipping of the pressure nut on the appliance gas pressure valve from nat to LP. then because propane/butane runs on higher pressure each pilot each top burner each oven burner will need adjustment. or else the bottom of the pans will be burnt. Down at the propane center they keep a guy around to set up them stoves to run on propane. Newer models that are propane stoves only with sealed burners do not need adjustment. if yours is a newer model I would suggest you get the propane dude out to check the pressure on the tank. That ain't gonna be it though unless you have problems with the heater too.

Answer 3

I suspect she has the wrong 'orface' installed in her stove. There are two types of gas used in home heating and cooking, butane and propane. These two types have different oxygen levels required for the complete clean burning. Not the right mixture and the flame burns dirty and creates the black stains you speak of.

Her gas providor will most likely come out and fix this problem for her for free. If not, contact the manufactorer of the appliance, generally both orfaces are provided with the appliance so she just has to find it and put in the right on.

Answer 4

wrkey and teddy bear junior or both right....Stoves have certain orifaces for different fuels....Propane and natural gas....some stoves have a adjustable oriface..and some have a fixed size orifice for propane or natural gas..if the stove is new and the seller installed the stove..They should come adjust the orifice free of charge..this can be dangerous..we moved to a house once that our heaters were set for natural gas..and we moved to a propane supplied house.. First night i went to sleep in living room on the couch(for our stuff was still in boxes etc)...when i woke up the heater i turned on turned the complete room totally black..i was black and rushed to the hospital for carbon monixide poisoning.. it is a simple solution to fix...but a dangerous oine to have..The gas company may possibly adjust it for you

Answer 5

A simple adjustment of the orifice, she's getting to much air.
