three heat zones are-
torrid zone
panic zone
· Reduction zone · Heat absorption zone · Fusion zone · Combustion zone
name one place which comes under torrid zone
By the SUNS ENERGY. (Which makes it hotter and hotter.)
convective and radiant heat transfer
The heat zone is the side facing the sun.
The blast furnace is typically divided into three main zones: the top zone (stack), the middle zone (bustle), and the bottom zone (hearth). The top zone is where raw materials are charged into the furnace and combustion of coke occurs. The middle zone is where gases and heat transfer occurs, and the bottom zone is where molten metal is collected.
The smoke or heat detectors have a 128 wireless zone. It is also stated that the detectors that have a 128 wireless zone also provide both real time and event scheduling capabilities.
The torrid zone receive maximum amount of heat because the sun rays comes straight to the earth.
About 75% of heat is generated in the shear zone
It is the heat affected zone. It differs in every weld. but a good rule of thumb is .25" on either side of the weld
