Water boiling test
This test is carried out as per the guidelines given in the Water Boiling Test (WBT).
There are two types of tests carried out namely cold start and hot start. In cold start test, initially 5 L of water is taken in a cylindrical pot and placed in the stove.
The briquettes start to burn and the fuel for combustion is supplied at regular intervals of time to maintain the burning
rate.
This is carried on until the water reaches the boiling stage.
The firing is stopped in the combustion chamber when it reaches the boiling stage and the ash and remaining briquette
is removed from the combustion chamber.
Now the same procedure is repeated for hot start test.
At this stage, the hot water available in the pot is replaced with freshwater at ambient temperature, but the stove and pot will remain hot.
The ash produced in the combustion process is regularly removed from the combustion chamber and disposed.
In each test amount of fuel used and time taken to reach the boiling point are noted.
The temperature is recorded by the mercury in glass thermometer for every 10 min.
A digital stopwatch is used to measure the time required to reach the boiling point of water in the pot.
