How are impurities generally removed from HRT boilers?

The removal of impurities from HRT (High-Temperature Reactor) boilers typically involves specifically designed procedures to ensure the integrity and efficiency of the boiler system. The correct method in this context is through the inclination of the boiler for drainage. This technique allows for gravity to assist in the removal of sediment and impurities that may settle at the bottom of the boiler.

Inclining the boiler facilitates the effective drainage of accumulated impurities, ensuring that the boiler can operate at optimum conditions without interruptions caused by fouling or scaling from these materials. It is a practical approach that relies on the physical properties of the system rather than relying solely on chemical or water-based methods.

While flushing with water and using chemical processes may be employed in other scenarios, they do not directly address the simple and effective method of leveraging gravity through inclination. Heating to high temperatures, on the other hand, may serve to change the state of some impurities, but it does not guarantee their removal, particularly in the case of solid residues. Therefore, the inclination for drainage stands out as the most reliable and direct method for impurity removal in HRT boilers.
