Thermal oil heaters

PIROBLOC thermal oil heaters are designed in compliance with international standards. We manufacture a wide range of thermal fluid heaters that can be fully customized to meet each customer’s specific requirements.

They can be supplied in horizontal or vertical configurations. Functionally, there is no difference between the two; the choice depends mainly on the available floor space, installation height, and ease of maintenance.

Our hot oil boilers can operate using liquid fuels (such as fuel oil or diesel) and/or gaseous fuels (including natural gas, propane, and others).

The thermal oil boiler is the central component of a thermal fluid heating system. It heats the thermal fluid and circulates it to deliver energy to various processes within a closed-loop system.

Key Features:

  • Automatic burner startup
  • Indirect temperature control

Advantages of a Hot Oil Heating System

Safety

Our thermal fluid heaters operate without pressure or water, eliminating common issues found in steam based systems such as leaks, corrosion, and the need for water treatment.

 

Low Maintenance Requirements

Thermal oil systems require very little maintenance. They also provide up to 20% fuel savings compared to steam systems, thanks to their closed-circuit design, which minimizes energy losses. More than 90% of the fuel’s energy is effectively used for heating.

 

High Efficiency

Hot oil heating systems deliver excellent efficiency due to consistent temperature distribution throughout the entire production process.

Construction Features

Our thermal oil heaters are cylindrical in shape and heat the thermal fluid as it circulates through two concentric coils, where combustion of the liquid fuel occurs via a burner mounted on the front wall.

Between the two metal casings, a layer of high-density rock wool insulation maintains low external surface temperatures (30-40°C). This minimizes heat loss and prevents accidental contact burns.

The burner flame is directed into a combustion chamber carefully designed to match the flame’s geometry. Combustion gases travel at high speed around the coils, changing direction several times to enhance heat exchange before being expelled through the chimney at the outlet end of the unit.

Coil System

Each coil may consist of two, three, four, or more stages, depending on the model. Maintaining a rapid flow of thermal fluid through these coils is crucial to ensure efficient heat transfer and to prevent overheating or damage to the piping.

Operation of thermal oil heaters

At the start of the heating process, the thermal fluid first flows through the outer coil, where heat is transferred primarily by convection. It then passes through the inner coil, where heat transfer occurs mainly by radiation. This dual-stage design provides excellent overall energy efficiency.

The front cover of the unit encloses the exhaust gases between the coils and includes openings for the passage of pipes. Each pipe is connected to the main collectors, which in turn are joined to the external circuit via flanges.

This cover also seals the combustion chamber, where the burner is mounted. An access door allows easy entry for inspection or maintenance when required.
