The Firing Process for Making Ceramics -

Firing is the process of bringing clay and glazes up to a high temperature. The final aim is to heat the object to the point that the clay and glazes are "mature"—that is, that they have reached their optimal level of melting. To the human eye, pots and other clay objects do not look melted; the melting that occurs is on the molecular

Starting and Stopping Boiler - Marine Engineering

The water level rises due to expansion when the boiler is heated. If the temperature difference between the boiler and feed water exceeds approximately 50ºC, the boiler must be filled very slowly. When filling a pressure less boiler, the shut-off valve after the feed water pump must be throttled. Otherwise the pump motor will be overloaded.

Boiler operation training - Learn how to start a boiler

The standard warm-up curve for a typical boiler is not to increase the boiler water temperature over 100°F per hour. Check your manufacturers' guidelines. After the pressure reaches 10-15 PSIG, close the drum vent and slowly bring the boiler up to operating pressure. Collect a boiler water sample and test for the proper chemical concentrations.

Boiler blowdown - Wikipedia

2019-5-29 · Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of
