Desuperheating is a critical process in steam generation and power systems. It refers to the practice of reducing the temperature of superheated steam to a point closer to its saturation temperature. The objective is to ensure steam quality, improve system efficiency, and protect downstream equipment.
Control Principle:
Sensing and Feedback: The primary control strategy involves continuous sensing of the superheated steam temperature after the superheater. This data is sent as feedback to ...
The manufacturers with different scales will have different price policy on the natural gas boilers. The prices of natural gas steam boilers in some large boiler enterprises are higher, while those in some small enterprises are lower. The difference lies in the raw materials, the production process, the quality of employees, and the service management of the company.
Boiler water circulation refers to the circulating flow of water and steam-water mixture on the evaporating heating surface of boiler. What is the working principle of the latest water circulation system of boiler?
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
If the final temperature of feed water doesn’t reach the saturated temperature after being heated by an economizer, (that is, the feed water has not reached the boiling state), we call the economizer as a nonsteaming economizer. Generally, the final temperature is 30-50℃ lower than the saturated temperature.
The main sectors in which industrial steam boilers are used are:
Food, in industrial bakeries or baby food (as an example)
Textile, in rotary dryers
Chemical, for reactors or storage
Pharmaceutical, for the manufacture of medicines
Cosmetics, for the production of perfumes and creams
Stationery and printing, in drying tunnels
The cement industry, for the manufacture of cement parts
Oil, for the storage and distribution of heavy oils
Wood, involved in the process of melanin production
Hospitals and hotels, especially in the laundry and kitchen areas
Automotive and surface treatment, for the final metal finishing.
(Question details) Specific performance:There is hammer sound in the oil inlet pipe, and the pointer of the inlet and outlet pressure gauge fluctuates.Answers: Cause of failure:The system contains gas and moisture.Troubleshooting:(1) Exhaust air.(2) Cook oil.
