1. Introduction to boiler structure

Zhongrui pressure-bearing hot water boiler is an electromechanical integration equipment, which consists of boiler body, burner, electric control cabinet, feed water pump and pipeline valve instrument. The unit is equipped with imported European burners. The unit body adopts the horizontal internal combustion three-return wet-back type of mature structure. The fuel (oil/gas) is sprayed from the burner through the pressure atomization at high speed, and it is slightly positive in the furnace. Compressed combustion, the high-temperature flue gas after combustion is transferred into the second return pipe to the front smoke box after the radiation heat transfer in the furnace, and then converted to the third return pipe by 180o degrees, and then discharged into the chimney through the rear smoke box. .

2. Boiler body technology advantages

In the layout of the convective heat transfer pipe area, the traditional two- and three-return "equal flow rate" design viewpoint was abandoned, and the "equal resistance" design new idea was used to arrange the convective heat transfer surface, which broke through the design of the furnace The traditional design idea of the diameter of the flame to determine the diameter of the furnace is to use a large corrugated furnace structure, greatly increase the radiation heat transfer area, and reduce the NOx emissions. The threaded pipe technology is applied in the convection heat exchange pipe section, and the boiler efficiency reaches 89.2%, which greatly improves the boiler efficiency. The smoke box adopts a double-sealed small smoke chamber structure to prevent smoke leakage, which is convenient for the user to repair. The heat preservation adopts aluminum silicate fiber felt, and the heat preservation effect is good. Since we have done a lot of work in combustion and heat transfer, we have adopted some new structures and new technologies, which have greatly reduced the size of the product, reduced the space occupied by the machine room, and reduced the weight.

3. Introduction to the characteristics of the boiler

High security and reliability

The boiler combustion chamber adopts corrugated furnace and has good thermal expansion performance. The combustion chamber is equipped with an explosion-proof door. The furnace body is equipped with high-sensitivity temperature, pressure, water level sensing and transmission components, and is connected to the programmable controller (PLC). ), Industrial Computer (IPC), constitutes a high-reliability multi-security protection control system to ensure the safe operation of the boiler; the boiler water volume is large, the operation is stable and reliable, and the heating quality is high.

Energy efficient

The boiler adopts a large furnace and a corrugated furnace structure, which increases the radiation heat transfer area and facilitates the full combustion of the fuel. The artificial neural network-based fuzzy control technology and the world famous brand burner are used to realize the automatic adjustment of combustion according to temperature and pressure, so that the boiler can operate efficiently and economically under different conditions, and the fuel consumption is minimized. .

Conducive to environmental protection

The low NOX combustion technology is used to optimize the boiler structure design, and the boiler combustion condition is automatically adjusted through the flue gas detection, thereby ensuring that the boiler flue gas emission meets the requirements of environmental protection in China and the world, and the running noise is low.

Easy installation and maintenance

The front and rear smoke boxes of the boiler adopt movable double sealing structure, which is convenient for inspection, maintenance and cleaning of the boiler interior. The whole boiler is fast installed, no vibration is running, and the installation is convenient and quick. The boiler computer controller can automatically record the time and cause of the fault, which is convenient. Maintenance personnel perform maintenance.

Rich intelligent control and network expansion

The advanced artificial intelligence control system engineering can carry out intelligent control of multiple boiler operating loads. The system interface can also be interconnected with intelligent building and industrial automation network, and implement remote monitoring function. The controller is full of Chinese, man-machine dialogue, multi-level Chinese menu and fault maintenance guide, and the operation is simple.

It provides production steam for food processing, printing and dyeing, pharmaceutical and other industries, provides disinfection steam for medical institutions, provides steam for heating of other enterprises and hotels, and provides domestic water through water tank heating.
