many time simmering test can give a misleading result about the efficiency of
the cookstove.  During the summering phase the vessel gets the thermal
energy from two sources one is from the fuel and another one is from the stored heat, which is released from the cookstove material. Hence when we quote the efficiency of the cookstove, it
should be the fraction of the total energy input (sensible heat + latent heat) transferred
to the vessel over the total energy input , during the complete WBT. Simmering phase
test cannot be dropped from WBT, even though it is not the only parameter used
to evaluate the performance of the cookstove. But, simmering phase is an important
part of cooking practice. During the actual cooking, the stove is not operated
only at high power. For example, boiling milk is a tricky process and control
over firepower is very important. When a cook can boil the milk without
spillover, it is considered that the stove and cook are good, in controlling
the fire power.</span></p>
