Features of electric heating boilers

Thread Content

Features: Electric heating boilers are products of world-class standard, featuring economy, energy efficiency, safety, high performance, low failure rates, and easy maintenance, all achieved through the use of the latest electric heating technologies and control system designs. Fully automatic intelligent control technology, unattended operation ； Flexible operation mode, which can be set to manual or automatic ； The automatic start date and operating hours of the boiler can be set as needed; up to ten different operating periods per day can be defined, allowing the boiler to automatically activate the various heating elements at different times. The heating elements are switched on and off in a cyclic manner, ensuring that each contactor is used for equal amounts of time and with equal frequency, thereby extending the service life of the equipment ； Simulation control algorithm: automatic temperature (pressure) PID, calculation, and tracking functions, which ensure the automatic start and stop of feed pumps and circulation pumps in response to changes in load ； It can also be controlled manually ； Chain closure function ； Alarm function: Automatic alarm in case of abnormal conditions ； After the alarm bell stops ringing, the fault remains unresolved, and the alarm goes off again ； Aesthetic design: The boiler’s outer casing features a frame-mounted structure, with its entire outer surface coated in plastic paint, giving it a stylish and attractive appearance ； Eco-friendly operation: noise-free, pollution-free, high thermal efficiency. The boiler body is made of high-quality, efficient insulation materials, resulting in low heat loss; the thermal efficiency is over 98% ； Its compact structure, professionally rational design, and advanced manufacturing processes result in a boiler that occupies less space, thus saving area ； A wide range of models available (electric hot water boilers, electric steam boilers, electric heat storage boilers). Features of the boiler body: High-quality boiler steel plates are used, and it is meticulously manufactured in accordance with industrial boiler manufacturing standards ； Both the longitudinal and circumferential welds of the furnace body are welded automatically, while the longitudinal and circumferential welds of the boiler are inspected using X-ray testing ； The boiler body is made of high-quality and efficient insulation materials, resulting in low heat loss and a thermal efficiency of over 98%. The boiler unit and control box are supplied as a set, making installation simple. Features of electric heating elements: Electric heating elements with a low surface heat load, meeting the requirements of JB/2379-93 and the Technical Specifications for Metal Tubular Electric Heating Elements. High-quality heating wire is used ； The outer tube is made of seamless steel pipe or stainless steel pipe with a wall thickness of 2 mm; the filler is high-purity magnesium dioxide powder, ensuring a long service life ； Each component is subjected to hydrostatic and voltage resistance tests ； Each group of electric heating elements is connected using a centralized flange connection and operates independently; they feature a simple structure, high mechanical strength, safety and reliability, easy replacement, and a long service life. Features of the control system: The control system used in the Sanheng fully automatic electric heating boilers is divided into levels such as 2-level, 4-level, 8-level, 20-level, 24-level, and 48-level, depending on the type of boiler. It enables electronic automatic tracking and adjustment of temperature (or pressure); automatic as well as manual settings are possible while maintaining stable heat supply. Isolating switches are also installed to facilitate operation and maintenance. It features various safety protection functions to ensure the safe operation of the boiler: it automatically stops heating when the electric boiler loses water ； When the temperature of the electric hot water boiler exceeds the set value, an alarm is issued and heating is stopped immediately ； If the water level in the electric steam boiler is too high/low, an alarm is issued and heating is stopped immediately ； When a short circuit occurs in the heating element of an electric boiler, stop operating that unit immediately and cut off the power supply ； When a phase is lost in one of the heating elements of an electric heating boiler, that element should be stopped from operating immediately and the power supply to it should be cut off. Application areas: ① Electric steam boilers are widely used in industrial production as well as in enterprises and institutions to supply the steam required for production and daily activities ； ②Electric hot water boilers are widely used as auxiliary heat sources in the chemical industry and oil refineries, as well as for heating, air conditioning, hot water supply, and providing domestic hot water in buildings such as luxury hotels and restaurants, office buildings, schools, research facilities, and hospital outpatient wards.
