Detailed description of electric boiler

Purpose of electric power heating. Electric boiler is to power as an energy source, the use of electrical resistance heating or electromagnetic induction heating, through the boiler's heat transfer parts of the heat medium water or organic heat carriers (thermal oil) heated to a certain parameter (temperature, pressure), the output to the outside with the rated quality of a thermal energy mechanical equipment. Revised by the State Council promulgated the "Regulations on the Safety Supervision of Special Equipment" in the definition of the boiler: boiler, refers to the use of various fuels, electricity or other energy sources, will be filled with liquid heated to a certain parameter, and carry a certain pressure of the closed equipment, the scope of which is provided for the volume is greater than or equal to the 30L pressurized steam boiler; outlet water pressure is greater than or equal to 0.1MPa (gauge), and the rated power is greater than or equal to 0.1MW. Or equal to 0.1MW pressurized hot water boilers, organic heat carrier boilers. In other words, no matter what fuel is used, the scope of its provisions are the same, just a different fuel heat source. Electric boilers must likewise follow the provisions of the "Regulations on the Safety Supervision of Special Equipment".

For the volume greater than or equal to 30L steam boiler, the user must be registered with the local quality and technical supervision for the boiler license, and every year to accept the annual inspection of the license.

For volume less than 30L steam boiler, we are accustomed to call the inspection-free small steam boiler (also known as steam generator), do not need to apply for a license. For atmospheric hot water boiler, no matter how large the volume is, do not need to apply for a boiler license. 1, boiler design, manufacturing in strict accordance with the "Steam Boiler Safety Supervision Regulations" and "General Technical Conditions for Industrial Boilers", "pot shell boiler body manufacturing technical conditions" requirements are strictly enforced.

2, fully automatic intelligent control technology, without the need for manned. Flexible working mode, can be set to manual or automatic mode.

3, the boiler can be set according to the need for automatic operation of the time period, a day can be set up a number of different working hours, so that the boiler automatically time-sharing start the heating group, the heating group cycle switching, so that the use of the time and frequency of each contactor is the same, to extend the service life of the equipment.

4, the controller on the water temperature or pressure automatic control, calculation, tracking, can be in the load change on the feed pump, the electric heating pipe for automatic start-stop control, but also can be manually controlled (see below).

5, with a complete number of protection functions, leakage protection, water shortage protection, grounding protection, steam overpressure protection, overcurrent protection, power protection, etc., the boiler is automatically protected, safe to home.

6, small boiler body, electromechanical integration, easy to install and mating; large boiler body and electronic control of the split boiler design, to eliminate the electrical control part of the furnace body by the high temperature, to ensure the stable operation of the electronic control devices.

7, in line with JB/2379-93 and the "metal tubular electric heating element technical conditions," the requirements of the low surface heat load electric heating element. High-quality electric heating wire jacket thickened stainless steel tube, tube filled with high-purity magnesium dioxide powder, electric heating tube with a long service life. Each group of electric heating element is connected by flange, featuring simple structure, high mechanical strength, safety and reliability, and convenient replacement.

8, compact structure, scientific and reasonable design and advanced manufacturing technology, so that the boiler occupies a small space, easy to transport and save the use of space.

9, no noise, no pollution, high thermal efficiency, the boiler body is insulated with high-quality high-efficiency insulation materials, heat loss is small, energy saving.

10, boiler packaging using famous color plate package design, beautiful appearance, not easy to rust.

11, automatic electric steam boiler/electrically heated steam boiler is widely used in hospitals, schools, textile factories, garment factories, clothing supermarkets, garment factories, dry cleaners, restaurants, hotels, burger stores, hotels, canteens, restaurants, food factories, beverage factories, soybean factories, meat factories, canning factories, distilleries, pharmaceutical factories, packaging plants, building materials factories, paint factories, beauty parlors, bathing centers, sauna, Vegetable dehydration, steam room and other places. Adopt YLZK series boiler computer controller. Absorption of foreign advanced technology, combined with the domestic boiler control automation of various needs and specific applications of the current situation, the use of modern computer control technology, and the introduction of a new generation of boiler controller. Applicable to steam boilers, hot water boilers and thermal oil furnace automatic control, with high reliability, high degree of automation, easy to use, easy to operate, feature-rich, flexible control, beautiful styling, high performance-price ratio.

This machine adopts intelligent modular industrial computer (iPC) as the core of the control system. Intelligent Modular Industrial PC (iPC) is a serial bus-based industrial control computer system composed of a variety of modules. Because of the serial bus, it has more advantages than the parallel bus (such as STD, PC104, ISA, etc.) used in the past. Each of its modules is an intelligent unit with a microprocessor (CPU), which itself has powerful programmable functions and can independently complete a variety of complex unit functions, and is the most advanced product in the domestic boiler computer controller.

With boiler water temperature control, boiler water level control, return water temperature detection, secondary return electric adjustment valve control, water shortage protection, over-temperature protection, timing control and other automatic control functions.
