Online monitoring of the two-dimensional temperature field

22/01/2015 · Online monitoring of the temperature field is crucial to optimally adjust combustion within a boiler. In this paper, acoustic computed tomography (CT) technology was used to obtain the temperature profile of a furnace cross-section. The physical principles behind acoustic CT, acoustic signals and time delay estimation were studied.

17/02/2017 · The boiler can only output hot water on the primary circuit at one specific temperature at a particular point in time; and this will be the higher of the temperatures required to satisfy Demand. CT/VT valves are a method of reducing the boiler flow temperature for heating circuits that need to run at a lower temperature.

Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion. This combustion takes place in the combustion chamber,

In a wet central heating system a boiler heats the water, which is usually pumped around a circuit of pipes to radiators throughout the house. Each radiator has valves that control the rate at which the water flows through them, this controls the amount of time the water spends in the radiator - and the amount of heat that's given off.

08/04/2004 · The principle is that after completing its cycle in the first engine, the working fluid is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency of the system can be
