Causes of boiler explosion - safety first!

The principal causes of explosions, in fact the only causes, are deficiency of strength in the shell or other parts of the boilers, over-pressure and over-heating. Deficiency of strength in steam boilers may be due to original defects, bad workmanship, deterioration from use or mismanagement."

"Cause.-Boiler explosions are always due to the fact that some part of the boiler is, for some reason, too weak to withstand the pressure to which it is subjected. This may be due to one of two causes: Either the boiler is not strong enough to safely carry its proper working pressure, or else the pressure has been allowed to rise above the usual point by the sticking of the safety valves, or some similar cause"

Boiler explosions are common in sinking ships once the superheated boiler touches cold sea water, as the sudden cooling of the superheated metal causes it to crack; for instance, when the SS Ben Lomond was torpedoed by a U-boat, the torpedoes and resulting boiler explosion caused the ship to go down in two minutes, leaving Poon Lim as the only survivor in a complement of 54 crew.

Water heating - facts

Circulating hot water can be used for central heating. Sometimes these systems are called hydronic heating systems.15

Common components of a central heating system using water-circulation include:

A supply of fuel, electric power or district heating supply lines
A Boiler (or a heat exchanger for district heating) which heats water in the system
Pump to circulate the water
Radiators which are wall-mounted panels through which the heated water passes in order to release heat into rooms.
The circulating water systems use a closed loop; the same water is heated and then reheated. A sealed system provides a form of central heating in which the water used for heating circulates independently of the building's normal water supply.

Heating systems in the United Kingdom and in other parts of Europe commonly combine the needs of space heating with domestic hot-water heating. These systems occur less commonly in the USA. In this case, the heated water in a sealed system flows through a heat exchanger in a hot-water tank or hot-water cylinder where it heats water from the regular potable water supply for use at hot-water taps or appliances such as washing machines or dishwashers.

range of hydraulic works in a block

Plumbers working in a cooperative housing standard working hours from eight hours to the seventeenth or eighteenth. In such a time they can also perform plumbing work in a block of flats. More work done in a block must be well organized in such a way that it can be performed as soon as possible with the greatest respect for the rights of the people to preserve their privacy and quiet in the early morning. The tasks of the executives of the association must also ensure the safety of residents of the block during the works. They can apply to do the second division of water, clean water and sewage network or even replacement of water meters in all areas.
