introduces a tDa diagram obtained by analytical solution of a simple heat transfer model of gas quenching, which shows the relationship between the cooling time tθ when core temperature of queched part cools to specific temperature, dimension D of quenched part and heat transfer coefficienta. of...
The cooler is a device, container, or room that cools air through the evaporation of water or keeps it cool. A furnace is a tool for heating a continuous current of air through a fire within the apparatus without mingling the fresh air with combustion products. The boiler is a closed vess...
However, the residual oil heated by the coking furnace is used to heat the feed, so it is not included in the pinch analysis. Furthermore, a new pinch diagram is presented in Fig. 4d in which the cold streams don't include the deaerated water. On this figure, the maximum feed ...
a relay system.relays and a thyristor which allows adjustment disorder after diagrams time furnace temperature (t - t) of the heat cycle.being easily adaptable to any heat treatment furnace.use in production leads to increased productivity at work, getting some significant energy savings in electric...
It has been mentioned in Section 4.8 that a stack is used for discharging a waste gas stream at a suitable height from the ground. Once discharged, the constituents (including the pollutants, if any) of the waste gas get dispersed. Some portions of those diffuse back to the eart...
The high pressure in the crucible is supported by the pressure of the contaminated atmosphere of the furnace of an internally heated, specifically designed autoclave. A description is given of the complete pressure system including two autoclaves (one for growth one for purification), a calibrated...
the furnace body is made of high-quality aluminum silicate fiber and refractory mud for insulation to control the furnace body temperature below 45℃ and control the heat loss; with the additional energy-saving device at the end of the flue gas duct, the boiler thermal efficiency can be improv...

Condenseris a device for reducing a gas or vapor to a liquid. Furnaceis a device used for heating. The name derives from Latin fornax, oven. Boileris a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. ...
The alloys were hot rolled at 800°C and then subjected to various heat treatments. Samples from hot-rolled alloys were given solution-treatment in β and α + β phase fields, respectively followed by water quenching and furnace cooling. The... 被引量: 858 年份: 1987 ...
