A hallmark of our helical coil heater is high thermal efficiency. Thermal efficiencies of our standard heaters range up to 85 percent LHV, depending upon fluid outlet temperature and fuel. Thermal efficiency is the total amount of heat produced by the burner versus the portion actually transferred to thermal fluid flowing through the coil.
Most synthetic thermal fluids have a significant advantage over mineral oils in heat transfer efficiency at temperatures between 150°C and 260°C. Above this temperature range (up to 300°C), some mineral heat transfer fluids narrow the gap with highly refined paraffinic / naphthenic white oils.

In most process heaters, the major part of the heat transfer from the hot gases to the tubes is by radiation. To calculate the radiative component it is necessary to know the effective emissivity, ε g, of the combustion gases (typical value 0.25).This is dependent on the ratio of the partial pressures of CO 2 and H 2, the temperatures of the gas and the radiation source and the …
Dec 23, 2021 · A relatively hot (480°F [250°C]) working fluid then exits the heat exchanger and is piped to an ORC plant, which takes the energy out of the 482°F fluid and returns it at 300°F, producing electricity. As a result of this process, producers can generate electricity to offset electrical demand.
Oct 25, 2021 · In high temperature applications such as those found in chemical or gas processing, heat transfer in industrial boilers, furnaces and ovens is achieved via direct firing into tubes. As one would expect, monitoring the temperature — by measuring the temperature of the tubes inside the industrial furnace, boiler or oven — is critical.
Oct 30, 2018 · Synthetic heat transfer fluids, such as a silicone, have a lower propensity to form carbon than mineral-based oils, offering better heat transfer efficiency and thermal stability. They are also more resistant to fouling, which means they tend to form less coke on the internal pipework and heater. For example, a eutectic-based fluid containing ...

Heat Convection Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law).Hot water is likewise less dense than cold water and rises, causing …

The primary mechanisms used for cooling electrical enclosures are as follows: Conduction: This is the transfer of heat through a solid. For example, heat generated inside an enclosure is transferred to the outer surface by means of conduction. Convection: Convection is the transfer of heat from a surface by means of a fluid such as air.
In residential heating, convection is the mechanism by which heat is lost by warm air leaking to the outside when the doors are opened, or cold air leaking into the house through the cracks or openings in walls, windows, or doors. When cold air comes in contact with the heater in a room, it absorbs the heat and rises.

Fired Heaters, as the name specifies are obviously heaters or furnaces. They are pieces of equipment used in processing facilities (refineries, power plants, petrochemical complexes, etc) to heat fluids up to the desired temperature. So, the main purpose of fired heaters is to raise the temperature of the process fluid that flows through the tubes.
where the heat transfer coefficient, α, is only a function of the flow field. T w is the wall temperature and T r, the recovery or adiabatic wall temperature.The above is also true of the Boundary Layer energy equation, which is a particular case of the general energy equation. When fluids encounter solid boundaries, the fluid in contact with the wall is at rest and viscous …
