Remote diagnosis

Shanghai industrial boilers provide a one to one solution for different industry attributes and needs of customer enterprises.

Overall design of wireless monitoring system

The monitoring system consists of three parts: a boiler operating in the field, a wireless communication device, and a monitoring center server. The wireless communication device and the boiler are connected through a 232 interface, and the wireless communication device transmits the collected real-time data to the monitoring center through the wireless network. Since wireless transmission is not limited by distance, multiple wireless stations can be connected to one monitoring center at the same time, so one monitoring center can detect multiple boilers. The monitoring center software is mainly responsible for processing the data sent by the boiler and displaying it in real time on the computer. The monitoring center saves historical data. At the same time, the monitoring center will alarm the dangerous data that may appear in real time.

Industrial boiler monitoring demand

At present, there are hundreds of thousands of large and small boilers in operation in China. The boilers are widely used in electric power, heating, bathing and other industries. In the course of use, due to the negligence of the operator, the use of the boiler is often caused. The online wireless monitoring system of the boiler is to monitor the operation of the boiler in real time and online, and to warn the potential danger of the boiler in advance to avoid accidents. The system collects the operating state of the boiler's temperature, pressure, liquid level and so on in real time. When it is judged that the boiler is operating in a dangerous state, it will promptly alarm and take necessary operations.

Boiler knowledge

Shanghai industrial boilers provide a one to one solution for different industry attributes and needs of customer enterprises.

The boiler is an important heat supply equipment in the national economy. The power, machinery, metallurgy, chemical, textile, paper, food and other industries, as well as industrial and civil heating, require boilers to supply a large amount of heat.

The boiler is a device that heats the working medium (intermediate heat carrier) to a certain parameter by using the heat energy or other energy released by the combustion of the fuel. A boiler that is used to heat water to convert it into steam is called a steam boiler. A boiler that is used to heat water to increase the temperature to hot water is called a hot water boiler; and a boiler used to heat an organic heat carrier is called an organic heat carrier boiler.

Classification of boilers

一、 Classified by purpose

1. Power station boiler: used for power generation, mostly large-capacity, high-parameter boiler, fire chamber combustion, high efficiency, export working medium is superheated steam; 2. Industrial boiler: used for industrial production and heating, most of which are low pressure and low temperature Small-capacity boilers, burning of fire beds, low thermal efficiency, export, working fluid is called steam boiler, hot water boiler is called hot water boiler; 3. marine boiler; 4. locomotive boiler; 5. Steam injection boiler: used for steam injection thermal recovery of heavy oil in oil field, the export working medium is generally high pressure wet steam.

二、 Classified by structure

1. Fire tube boiler: flue gas flows through the fire tube, generally small capacity, low parameter boiler, low thermal efficiency, but simple structure, low water quality requirements, convenient operation and maintenance; 2. water tube boiler: steam water flows through the tube, can It can be made into a small-capacity, low-parameter boiler, and can also be made into a large-capacity, high-parameter boiler. Power station boilers are generally water tube boilers with high thermal efficiency, but also have high requirements on water quality and operating level.
