Boilers or generators are equipments that, by applying heat produced by the combustion of fuel which can be liquid, gaseous or solid, heat water till boiling temperature (in hot water boilers), or over 100ºC (in high pressure hot water boilers), or finally, they can produce a change of state from liquid to gaseous, in steam boilers. In thermal fluid boilers, heating is carried by other heat fluids different from water.
There is a huge range of options for hot oil boilers. Each of these designs is thought with a special application, environment, or budget in mind. Here we describe the important factors to consider when comparing heating options.
One of the techniques used for energy efficiency is the provision of digital modulating burners with continuous oxygen control. This enhancement results in an increase in performance of around 2% and a consequent reduction in fuel consumption. Furthermore, this system ensures a reduction in combustion product emissions and enhanced operational safety.
Thermal oils are fluids used to transfer heat from one place to another. The oil is heated using any burner or resistance method and passed through a heat transfer system for the use of this energy in places away from the heat source.
Basically HTF heaters are industrial hot oil boilers where a heat transfer fluid, HTF, is circulating into a two concentric helical coils. The combustion of a fuel as natural gas, light oil, heavy fuel oil, or other, produces a flame that heats these coils by convection and radiation. Even there are also available on the market dual burners in order to choice the more convenient fuel. Through main pumps the HFT Heaters supply heat transfer fluid at a certain temperature to the different consumers.
