The purpose of electric heating. Electric boiler is a kind of thermomechanical equipment which uses electricity as energy source, uses resistance heating or electromagnetic induction heating, and outputs rated working fluid when medium water or organic heat carrier (heat transfer oil) is heated to a certain parameter (temperature and pressure) through the heat exchange part of the boiler. In the Regulations on Safety Supervision of Special Equipment revised and promulgated by the State Council, the definition of boiler is: a boiler refers to a closed device that uses various fuels, electricity or other energy sources to heat the contained liquid to a certain parameter and bear a certain pressure, and its scope is defined as a pressurized steam boiler with a volume greater than or equal to 30L; Pressurized hot water boilers and organic heat carrier boilers with outlet water pressure greater than or equal to 0. 1 MPa and rated power greater than or equal to 0. 1 MW. That is to say, no matter what fuel is used, its prescribed range is the same, but the fuel heat source is different. Electric boilers must also comply with the provisions of the Regulations on Safety Supervision of Special Equipment.

For steam boilers with a volume greater than or equal to 30L, users must go to the local Bureau of Quality and Technical Supervision to register the boiler license and accept the annual inspection of the license.

For steam boilers with a volume of less than 30L, we are used to calling them inspection-free small steam boilers (also called steam generators), and we don't need to apply for use certificates. For atmospheric hot water boilers, no matter how big they are, there is no need to apply for a boiler license. 1. The boiler is designed and manufactured in strict accordance with the requirements of Safety Supervision Regulations for Steam Boilers, General Technical Conditions for Industrial Boilers and Technical Conditions for Manufacture of Shell Boilers.

2, fully automatic intelligent control technology, no need for special personnel on duty. Flexible working mode, which can be set to manual or automatic mode.

3. The automatic operation cycle of the boiler can be set as required, and several different working cycles can be set in one day, so that the boiler can automatically start each heating group in time-sharing, and the heating groups can be cyclically switched on and off, so that the service time and frequency of each contactor are the same, which can prolong the service life of the equipment.

4. The controller can automatically control, calculate and track the water temperature or pressure. When the load changes, it can automatically start and stop the feed water pump and electric heating pipe, or it can be manually controlled (see the figure below).

5. It has complete protection functions, such as leakage protection, water shortage protection, grounding protection, steam overpressure protection, overcurrent protection, power supply protection, etc. , boiler automatic protection, safe home.

6, the pot body is small, the electromechanical integration is convenient to install and match; The large boiler body and electrical control are designed separately to prevent the electrical control part from being affected by the high temperature of the boiler body and ensure the stable operation of the electrical control device.

7. Electric heating elements with low surface heat load are adopted, which meet the requirements of JB/2379-93 and Technical Requirements for Metal Tubular Electric Heating Elements. High-quality electric heating wire is covered with thick stainless steel tube, and the tube is filled with high-purity magnesium dioxide powder, which has long service life. Each group of electric heating elements is connected by flange, which has the characteristics of simple structure, high mechanical strength, safety and reliability, and convenient replacement.

8. Compact structure, scientific and reasonable design and advanced manufacturing technology make the boiler occupy less space, facilitate transportation and save space.

9, no noise, no pollution, high thermal efficiency, boiler body using high quality and efficient insulation materials, small heat loss, energy saving and consumption reduction.

10. The outer packaging of the boiler is wrapped with famous color plates, which has a beautiful appearance and is not easy to rust.

1 1, automatic electric steam boiler/electric steam boiler are widely used in hospitals, schools, textile factories, clothing factories, clothing supermarkets, clothing factories, dry cleaners, restaurants, hotels, steamed stuffed bun shops, hotels, canteens, restaurants, food factories, beverage factories, bean products factories, meat products factories, canneries, wineries and so on. The boiler controller adopts YLZK series computer controller. Absorbing foreign advanced technology, combining the various needs and specific application status of domestic boiler control automation, adopting modern computer control technology, a new generation of boiler controller is introduced. It is suitable for automatic control of steam boilers, hot water boilers and heat conduction oil furnace, and has the advantages of high reliability, high degree of automation, convenient use, simple operation, rich functions, flexible control, beautiful appearance and high cost performance.

The machine adopts intelligent modular industrial computer (iPC) as the core of the control system. Intelligent Modular Industrial Computer (iPC) is an industrial control computer system composed of multiple modules based on serial bus. Because it ISA serial bus, it has more advantages than previous parallel buses (such as STD, PC 104, ISA, etc.). ). Each module is an intelligent unit with a microprocessor (CPU), which has powerful programmable functions and can independently complete various complex unit functions. It is the most advanced product in domestic boiler computer controller.

It has automatic control functions such as boiler water temperature control, boiler water level control, backwater temperature detection, secondary backwater electric regulating valve control, water shortage protection, overtemperature protection and timing control.
