This term is the most important term in boiler operation and monitoring. The parameters of the blow down are to be maintained for particular diesel fired steam boiler. This is due to the fact that water inside the boiler gets continuously evaporated due to steam generation. Concentration of dissolve solid, inside the drum increases and reach beyond the limit, so carryover of solids along with steam can occur. To prevent boiler tube chocking and overheating of the boiler tubes the blow down is necessary. Good blow down management can extend XHJ boiler service life greatly.
S = Amount of solids (ppm)
B = E x S (m3 / hr.)/(C–S) % B = S/(C–S)
Blow down means, "lost heat"
This is because any water, which is getting drained from the boiler drum efficiency, will be at the saturation temperature of steam and this has been heated starting from water of ambient temperature. Hence any reduction in this quantity of water would mean corresponding saving of fuel which can be qualified.
