it causes scale on the inter walls of the tube
chemical is used in sub critical boiler that is tri sodium phosphate added in durm. The main purpose is raise in pH value , salt is converted in to sludge form
In water a lot of impurities are present when we use such water it will produce slice formation inside the tube of boiler due to which there is slice formation takes place and heat will not transfer properly . temperature of the boiler tubes are about 1400 degree centigrade.if heat is not flow properly through tubes then tubes will melt.
Oil and seawater can be separated using methods like skimming or using specialized equipment like oil-water separators. Skimming involves physically removing the oil from the surface of the seawater, while oil-water separators use a combination of gravity and filtration to separate the two substances. These methods help to minimize the environmental impact of oil spills in marine environments.
To detect a tube leak in a fire tube boiler, you can look for signs such as increased fuel consumption, reduced boiler efficiency, visible steam or water leakage from the tube, or unusual noises coming from the boiler. You may also conduct non-destructive testing methods like ultrasonic testing or using a thermal imaging camera to pinpoint the location of the leak. Regular inspection and maintenance are crucial to prevent and address tube leaks promptly.
A water pot boiler works by heating water in a closed container using a heat source such as a stove or electric element. The heat causes the water to boil and turn into steam, which then rises and transfers heat to the surrounding water. This process efficiently heats the water in the pot.
An economizer is used to heat boiler feedwater up closer to the temperature of the boiler water, using heat from the boiler exhaust gases, heat that would otherwise be wasted. The main reason is to improve the efficiency of the boiler. For every 44 degree F drop in exhaust gas temp. there is an 11 F rise in feedwater temperature and a 1% gain in boiler efficiency.
There are a few ways to do this. First is manually, using a pump and a throttle (globe) valve, while watching the gage glass. second and most commonly, using a one element, or three element, or plc controled feedwater level control and an automatic (pneumatic, hydraulic or electric) feedwater control valve. Thirdly, with an injector or inspirator manually control the feedwater flow while watching the gage glass; and fourth, using a float control switch cycle the feedwater pump on and off automatically. There may be even more methods of controlling the feedwater flow but these are most common.
easy .. do nothingg
To increase the efficiency of a Rankine cycle, you can: increase the boiler pressure to increase the temperature of the steam entering the turbine, lower the condenser pressure to improve the quality of the exhaust steam, and use regenerative feedwater heating to reduce heat losses. Additionally, using superheated steam can also improve the efficiency of the cycle.
Nop!But you can suck your girlfriends nipples!Remove her dress kiss on lips!I did that to ma girlfriend removing my t-shirt.
Yes
Using a metal detector.
Seawater and fresh water contains oxygen that fish absorb using their gill. So the substance is oxygen.
Because you are using the Hot water faster than the boiler can produce it. Turn the tap/faucet off a bit. Get the proper sized boiler
to cook food using steam pressure of course
Because if you don't it will leave mineral deposits in the boiler. This is why many boilers and water heaters have a sacrificial rod.
A double boiler is usually used to melt choclate. You can make one yourself by using two pots and boiling water.
