What is the difference between the operation of a automatic boiler and manual boiler?
boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
How do you prevent boiler explosion?
All boilers are made to a pressure specification and in most countries any pressure vessel over a certain size is required to be periodically inspected and pressure tested to ensure it is fit for purpose. In addition to being in sound condition, the boiler is also expected to have some form of pressure relief valve. This is of sufficient size to vent off excess pressure before it gets to an explosive situation. It is obviously important that the pressure of this device is set to a lower level than the ultimate pressure specification of the boiler. Even quite small boilers, like those in coffee makers need to be inspected. Some boilers are 'gas fired' such as home heating boilers. These have a device called a thermocouple that detects the flame and is linked to the gas valve. If the flame goes out, or the burner does not ignite when gas is released in the boiler, it will shut the gas off. Typically gas fired boilers have a number of devices that will shut off the gas in the event that something doesn't work. This means that if the gas supply pipe is in sound condition, the boiler itself cannot leak gas and cause an explosion.
Where do textile chemist work?
textile chemists work in ether a lab or an office.
Can a petrochemical engineer work in an oil company?
Petrochemical means petroleum based chemicals. So the place a petrochemical engineer is most likely to get work is an oil company.
What is Hardgrove grindability index?
The Hardgrove Grindability Index was developed in the 1930s from experimental work by R. Hardgrove to determine the relative difficulty of reducing various coals to a particle size required for efficient combustion in pulverized coal boiler furnaces. The HGI is now commonly applied to specifications for coal to be used in the iron making, cement and chemical processes. There are several different "standard" methods for the determination of HGI (e.g. - AS1038 Part 20:2002, and ASTM D409-2006), which can lead to significantly different results. Further, HGI is an empirical measure and not a physical proprty of coal; as such the results of any standard test have relatively low repeatability for a given coal sample. In general, the higher the HGI value, the more readily a coal can be reduced to smaller particle sizes.
How does a back boiler work scientifically?
A boiler works by heating water in an enclosed space. The expansion of water molecules as it transforms from a liquid state into a gaseous one causes the boiler to generate a vast amount of pressure. This is generally the science behind a back boiler.
How does a combination boiler work?
A combination boiler does two tasks, the first is to provide radiant heating to a building and the second is to provide hot water. The boiler can provide hot water to only one system at a time, but eliminates the need to have two boilers.
Can you cook pasta in a double boiler?
Pasta needs to cook in rapidly boiling water, so a double boiler won't work that well for cooking pasta.
Can you run your boiler with the water shut off?
For a while IF the boiler has an automatic low water cut off and other safety devices but if any fail you will have a melt down and an explosion
Can you incorporate a solid fuel back boiler into a pressure water system it would be nice not to have to use so much oil and take advatage of our wood burning stove?
Yes, If it is a pressurized system, the water from the back boiler and your oil or gas fired boiler can be mixed. This can also be achieved by using a water to water plate exchanger to preheat the return water from your heating devices. If you have a forced air heating system in the house, a coil can be placed in the main trunk line of the duct work and heated by circulated water from the back boiler.
What is boiler and how does it work?
A broiler is a mechanism that boils water that produces steam. The steam can be used for a purpose such as cooking foods.
How does a hydronic boiler work?
The boiler in a hydronic heating system is just a heat source. An electric or gas water heater could be used as well. Proper design and installation are the key attributes.
What are the consequences of low alkalinity in boiler water?
corrosion problems because of the acidity as well as the other water treatments may not work if the alkalinity is out of target
How does a home heating boiler work?
A home heating boiler is a woodburning water heating system that can potentially save you money on natural gas. If you cut your own wood and have an ample supply to burn, then a home heating boiler might be a great cost effective option.
Radiators are cold on second floor source of heat is a oil fired boiler?
The fuel does not matter, it would be more relevant to post if you are hot water or steam, that is where your problem lies. If steam try raising the boiler cutout pressure a little bit and if hot water look at the boiler pressure, does the pump work, is the coupling broken and do you have air in the system that needs to be bled?
Do you have to fill a hot water heat boiler?
There has to be water in either system for it to work, check with the manufacturer and provided documentation to discern proper water capacity.A hot water boiler (hydronics) as opposed to steam is a system that is filled with water and has an automatic feeder to make sure the boiler never dry firesA steam (vapor) system has a limited amount of water so it has space to make steam and can have a manual feeder BUT like a hydronic system much have a low water cut off to prevent dry firing
