First, here are a few definitions to establish a common framework for this discussion.
It takes 1 BTU/hr to raise 1 lb of water 1 deg F.
1 liter of water weights roughly 2 lbs, so it takes 2 BTU/hour to raise 1 litre 1 deg F.
Water at home temperature is 60 F, it will boils at 212 F. There is 152 F difference.
1 hour = 60 minutes = 3600 seconds.
So, to raise 1 litres of water from 60 F to boiling at 212 F would require 1*152*2=304 BTU/hour.
This analysis does not take into account any thermal loss (cooling) because the loss would vary based on outside temperature, material of the vessel, surface area of the opening, etc. Regardless if you use electricity or propane, insulating your hot liquor tank and brew kettle will help you achieve your target temperature more quickly and maintain that temperature with less energy.
Generally speaking propane burners are rated on BTU/hour or simple BTUs. They range from 35.000-200.000 BTU/hour. This is the amount of energy produced by burning the propane, but not necessarily transferred to heat the water. So, it is not a perfectly efficient transfer to your HLT or boiling kettle. There will be further loss from the vessel itself since it is not a perfect conductor. It is difficult to determine the actual amount of energy produced by the burning propane that actually makes its way into heating the water. Therefore, I will make an assumption that only 50% of the energy produced by a propane burner actually heats the water. A quick Google search turned up the King Kooker turkey fryer produces 54K BTUs/hr. Adjusting for efficiency, the propane burner provides 27,000 BTU/hr (from 54,000*50 % per hour). Based on this value, the propane burner could bring 2 lbs of 60 F water to boil at 212 F in (304/27,000*3600 seconds) = 40.53 seconds. Obviously, a more powerful burner will heat water more quickly, but with greater fuel consumption.

How much air is required to burn 1 kg of lpg?
Approximately 25 cubic meters of air is required to burn 1 kg of LPG completely. This is based on the stoichiometric ratio for the combustion reaction of LPG with oxygen.
How much LPG low pressure gas is required to melt 300kg in a furnace?
The amount of LPG low-pressure gas required to melt 300kg in a furnace depends on the efficiency of the furnace and the heating value of the LPG. It is recommended to consult a professional to calculate the precise amount needed for your specific setup.
How much natural gas required to produce 1 kg LPG?
It takes about 1.2 cubic meters of natural gas to produce 1 kilogram of LPG (liquefied petroleum gas). This conversion factor can vary depending on the efficiency of the production process and the composition of the natural gas.
Specific heat and latent heat of LPG?
The specific heat of LPG (liquefied petroleum gas) is approximately 2.0 kJ/kg°C. The latent heat of vaporization for LPG is around 440 kJ/kg at atmospheric pressure, which is the amount of energy required to convert 1 kg of LPG from liquid to gas at its boiling point without a change in temperature.
How does water get into LPG?
Liquefied Petroleum Gas (LPG) is synthesized by refining petroleum or "wet" natural gas, and is usually derived from fossil fuel sources, being manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground. If it comes from the ground, there always a water vapor component in the gas stream. The refiners try to remove as much water as economically possible, but a small percentage will remain with the gas. Since water is heavier than LPG and does not mix with it, it is possible to remove water from a storage vessel by venting it at the bottom. Ideally, the vessel should be chilled to cause most of the water to condense and settle to the bottom. The partial pressure of the LPG will force the heaviest liquid (water) out the vent valve first, followed by mostly LPG. If even drier gas is required, it can be forced through a drier that contains water adsorbent materials. When the drier is saturated with water it needs to be replaced. Small amounts of water don't impair the usefulness of LPG as a cooking or motor fuel. However, if it is to be used as a refrigerant, replacing R-22 in a domestic air conditioning system or R-134a in an automotive air conditioning system, it should be as dry as possible in order to prevent corrosion of the system components. For refrigerant use, highly refined liquefied propane is available from companies such as Duracool, so the end user need not be concerned with contaminating a refrigeration system with water.
How much LPG gas required for one cup of tea?
The amount of LPG gas required to boil water for one cup of tea is relatively small, typically around 0.1 to 0.2 kg of LPG. This estimate can vary based on the efficiency of the stove, the initial temperature of the water, and the specific boiling time. Generally, boiling about 200-250 ml of water for tea may use around 10-15 grams of LPG.

What pressure of lpg required for lpg burner?
2.75kpa, LPG burns 102MJ/h per m3
How much LPG low pressure gas is required to melt 300kg in a furnace?
The amount of LPG low-pressure gas required to melt 300kg in a furnace depends on the efficiency of the furnace and the heating value of the LPG. It is recommended to consult a professional to calculate the precise amount needed for your specific setup.
Does Mazda Axela comes factory fitted LPG?
Some versions of the Mazda Axela come with a factory fitted LPG. Most of these models are available in Korea and Japan where the LPG conversion is required by law.
How do convert 28 liter water tank to LPG liter?
Probably not a very sensible idea. Water tanks are unlikely to be rated for the pressures used for LPG tanks, and LPG, being both flammable and explosive, is not the stuff that you want to play with.
