A gas fired boiler is a product used to heat your water for homes as well as swimming pools, they are very ifficient and save energy thus lowering your electric bill. There is a down side to having a gas fired boiler being as the costs of gases has gone up greatly it would be harder to keep a gas fired boiler going for a middle class person
boiler use many type of working fluids like water, mercury, liquid sodium, etc., but steam generator works only with water as working fluid. hence all steam generator are boilers but all boilers are not steam generators...
Coil boilers work by having many steel or copper pipes surrounding the area to be heated, these pipes then have extremely hot steam running through them creating the boiling temperatures.
HgBr2 is mercury II bromide or mercuric bromide.
Different types of thermometer have to be used in different circumstances, for example the thermometer you stick in your mouth when you're ill would be of no use in a steam boiler or even in your oven as it would break. Mercury expands and contracts more than alcohol so it can show a greater range of temperatures.

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.
The Mira Event XS Power Shower cannot work with a combi boiler. This may cause damage to the Mira shower.
Stationary engineers and Boiler operators are some of the jobs that offfer on the job boiler training. Work opportunities are available at local chapters of the International Union of Operating Engineers.

Pasta needs to cook in rapidly boiling water, so a double boiler won't work that well for cooking pasta.
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.
While there may be an online school offering boiler training, working in the boiler industry requires extensive hands-on training and mechanical skills. Choosing an online school may not be the best way of acquiring the necessary job skills to successfully work as a boiler technician.
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.
the work of the condensor is to condense the hot steam and change its state so that it can be used again in boiler
Boiler can be classified as below
