Description of Electrical Hot Water Boiler/Hot Water Generator

An industrial electric hot water boiler is a heating device that uses electricity to heat and circulate hot water in industrial settings. It is functionally designed to provide a reliable and efficient source of hot water for various applications, including process heating, cleaning, and sterilization. The hot water boiler operates on the principle of forced circulation, where water is heated and circulated through a heat exchanger to transfer heat to the desired medium. It features a compact and clean design, making it suitable for installation in tight spaces. The electric hot water boiler is fully automatic, requiring minimal manual intervention and ensuring ease of use. Its high efficiency of up to 99% ensures efficient utilization of energy resources, resulting in lower energy costs. The electrical hot water boiler is also designed to comply with safety standards and regulations, making it a safe and reliable option for industrial heating applications.

Electrical Hot Water Boiler Working Principle

The working principle of an electrical hot water boiler is based on the principle of forced circulation. It involves the use of electricity to heat and circulate hot water through a closed loop system. The hot water boiler consists of a heat exchanger body that is complete with immersion type heating elements. As electricity flows through the heating elements, it generates heat that is transferred to the water in the system.

The heated water is then circulated through the closed loop system, which includes pipes, pumps, and valves. The circulating water transfers heat to the desired medium, such as a process stream, cleaning solution, or heating system. The heat transfer rate is optimized to ensure a high rate of heat release with low surface load and high fluid flow.

To maintain the desired temperature, the electric hot water boiler is equipped with a digital temperature indicator-cum-controller that measures and controls the heater’s ON/OFF condition. The boiler also includes a low-level switch in the tank that protects against low levels of water, resulting in the heater being turned off.

Overall, the working principle of an industrial electric hot water boiler is straightforward, reliable, and efficient. It provides a cost-effective and energy-efficient solution for heating water in various industrial applications.
