MCF * BTU = MMBTU
MMBTU * KWH = Heat rate
There are many factors. First of all, there is the temperature of the water. Next, the is the volume of water. Next there is the amount of pressure gradually built up in the boiler. Next you have the amount and speed at which heat is transferred to the water.
Divide heat added to the boiler between feedwater inlet and steam outlet by the kilowatt output of the generator at the generator terminals. Rate expressed in btu. See article.

E=MC2 + o2 + H20 = Heat rate
Heat flux is the primary performance paramater in boiler performance. Heat flux can be affected by many factors espacially by boiler tube fouling ( or exchange surfaces) that will considerably reduce heat exchange.

what are the 3 ways to transferred heat into a boiler
The heat transferred from flames to a boiler depends on several factors such as the temperature of the flames, the surface area of the boiler, and the efficiency of heat transfer. In general, the heat transfer occurs through convection and radiation, with the flames heating the boiler's surface which then heats the water inside.
I would recommend using a double boiler. If a double boiler is unavailable, I would heat it on low heat and stir it frequently.
