heat is transmitted by gravity between the boiler and cylinder ina hot water system. this is using the principle of?
lamont boiler is high pressure boiler & it'swork on high pressure at constant temprature
In modern boiler service systems today, many use a mechanical principle known as forced circulation. Boilers are forced to use this method as the pressure inside the boiler is very high, which means the boiler will have to manually force the water/liquid mixture to circulate so that any progress can be made.
With an indirect water heating system and cylinder, the water that circulates around the boiler, pipes and radiators is kept totally separate from the stored water in the cylinder that is used for bathing. From the outside the indirect cylinder looks identical to the direct cylinder save from two additional pipe connections on the side of the cylinder. Inside the cylinder a coil heat exchanger is installed, which allows hot water from the boiler to flow into the upper connection and leave at the lower connection to return to the boiler for re-heating. The hot water in the coil indirectly heats the water in the cylinder. A Direct Cylinder is heated by a source located within the cylinder - such as an electrical immersion heater. Because the Immersion Heater is heating the water 'directly' the cylinder is called a 'Direct Cylinder'. In a direct cylinder there are no other external heat sources.

Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
The Cornish Boiler only has one fire tube compared to the Lancashire Boiler's two.
the apparatus ( Marcet Boiler ) consist a cylinder surrounded with isolated substance in it electrically heated boiler which is used to heat up water and to measure the both of the temperature and pressure, & it contains thermometer & barometer & safety valve .
A furnace heats air; a boiler heats water. --The HVAC Veteran
A burner is the part of the boiler that creates and controls the flame that heats the water. If you meant difference between a boiler and a furnace, a boiler makes hot water and a furnace makes hot air.
In boiler the feed is only liquid but in reboiler the feed may be any liquid. second is that, reboiler do partial vapourization but the boiler does complete vapourization
