Rotary grate hot oil boilers are designed to provide efficient and safe heat generation and heat transfer at high temperatures. These boilers heat a heat transfer fluid, known as thermal oil, by burning solid fuels. The heated thermal oil is circulated through the heating system by pumps, ensuring efficient heat transfer. This design allows long distances between the boiler and the heat-consuming units, providing flexible installation options.

Rotary grate hot oil boilers are supported on a steel platform integrated with the rotary grate system. Depending on the boiler capacity, the system is designed as a two-pass or three-pass configuration. The boiler is centrally positioned on the rotary grate, and optimum combustion efficiency is achieved through properly designed refractory brick and refractory concrete applications.

Rotary grate hot oil boilers provide proportional temperature control by automatically adjusting the grate movement speed, fuel feeding rate, and combustion air fan speeds according to the required temperature. In addition, due to the characteristics of the thermal oil used in these systems, common issues such as corrosion and scaling in pipelines and equipment are minimized, resulting in higher operational efficiency and reduced maintenance requirements.
