Direct Fired Heaters are used for specific applications. We could consider Direct Fired Heaters basically as custom-designed equipment, given that the heat is directly transmitted to the product of the process, and any change in this characteristic could render the equipment ineffective for the new conditions of the process or even destroy the product or equipment due to unsuitability.

The determination of the heat transfer rates to or from a system and, therefore, the heating or cooling times and temperature variation is the subject of the science of heat transfer.

The term convection comes from the Latin convectare, which means to take to a place. In heat transfer, the concept of convection refers to the process of moving thermal energy from or to a solid by means of an adjacent fluid in motion, in the presence of a temperature gradient

P&ID is defined as a diagram of piping and instrumentation and it shows the process flow in pipes, as well as, the equipment installed and instrumentation.

In the analysis of heat transfer processes, some bodies can be considered to behave as a unit, with an internal temperature essentially uniform (although not constant) at all times during the heat transfer process.

When speaking about the transfer of any physical property, in general three basic concepts of transport are considered: molecular, advective and convective. The concept of convection is considered a combination of molecular transport and advective transport.

The American Society of Mechanical Engineers (ASME) created the ASME certificates, an internationally recognized certification for professionals in the sectors where standards have to comply with the maximum guarantee of design, manufacturing and quality.

Thermal fluid oils are basically used to carry heat from a given location to another, after being preheated by any method able to do it, whether if it is a burner, or resistance, etc. They are also called heat transfer fluids, of thermal transfer or, HTF from English.

It is an essential tool, from which will depend largely the correct operation of the installation. On many occasions, this tool also serves to define the scope of supply. So, the battery limits that determine the responsibility and the scope of each company involved (if it is the case).

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.

Expansion is the size variation of a body when the temperature at which is exposed changes. It’s very important to treat properly the absorption of expansion in thermal fluid installations.

The thermal fluid electric boilers from the hydraulic point of view, reasonably resemble to a shell and tube heat exchanger, wherein the tube bundle is replaced by the set of forks which are electrically feed to heat the oil circulating in the shell.

The thermal heating system represents a technological revolution in relation to other conventional systems. The industrial uses of thermal oil provide a wide range of advantages, allowing for advanced heat control systems, far greater performance and economy, which may be adapted to the specific and concrete needs of each industrial activity.

The rising cost of oil and climate change, in addition to a host of other social and environmental factors, have obliged humans to develop new high-performance power plants, in relation to which electric steam boilers play a major role. This device is a heat generator which uses electricity as a source of power instead of the traditional burning of combustibles.

With a correct sizing and the supplying of modulating burners, when the demand of power is low, the modulation of the burner complies consequently with that low demand, avoiding complete unemployment and the cooling of the combustion chamber for, immediately afterwards, returning to warm up it. That is to say, useless fuel consumption.

The white oil is obtained starting from paraffinic fractions of mixed base or naphthenic one, depending on the definitive use. The process is carried out for vacuum-distillation, followed by several refinement processes, included a final purification with catalytic regeneration. Their applications are specially important in products that have direct and forced contact with the human being, for what should be no toxic, not to stain and nor to contaminate.

In reference to the viscosity, it is considered from two points of view: separately and its variation in reference to the temperature.
The oils have advantages in comparison with other fluid, thanks to their better relation viscosity/temperature, that it is expressed in terms of the Index of Viscosity. It is calculated by an empirical formula from viscosities at 40º and at 100º C. A high value means a small change of viscosity in relation to the temperature.

PIROBLOC already has in operation a new thermal fluid heater in which their components fulfill ATEX rules (for facilities in atmospheres with explosion risk). In this occasion, we have supplied again for the petrochemical sector, a…
