The rubber ball cleaning device is the best equipment for effectively cleaning the condenser heat exchange tubes during the operation of a steam turbine generator set. The performance of the device directly affects the cleanliness and heat transfer efficiency of the condenser. It is an essential equipment for improving the economy of power plants and ensuring the safe operation of condensers.

The ball collecting net is a key equipment of the rubber ball cleaning system, which functions to separate the rubber balls from the cooling water and ensure that they do not leak or get stuck. The ball collection net is installed on the outlet pipe section of the cooling water. When the water carrying rubber balls flows out of the condenser and passes through the ball collection net, the balls are recovered and led out from the ball collection net through the outlet pipe. The grid plate of the ball collecting net can rotate. When the rubber ball circulates, the net plate is placed in the "ball collecting" position. When the rubber ball is not in use for cleaning, the net plate is placed in the "backwashing" position. At this time, the debris on the net plate is washed away by the water, while reducing the water resistance of the net plate. The operation positioning of the net board is ensured by an electric actuator (small ball collecting nets are manually operated).

Lianyungang Huaneng Electric Power has newly launched the KN type air cooler, which belongs to the bimetallic rolling plate structure and has the characteristics of good cooling effect and good anti vibration performance!

Oil cooler is a commonly used oil cooling equipment in power systems, and is also suitable for sectors such as metallurgy, chemical industry, mining, light industry, and heavy industry. Mainly used for circulating cooling in equipment lubricating oil, transmission system oil, turbine oil, and grinding kerosene oil systems.

The coil header structure of the high-pressure heater adopts a collection and distribution system with five pipe openings welded to the header. The steam side is divided into three parts: the superheated steam cooling section, the condensation section, and the hydrophobic cooling section by a partition and an inner cylinder structure. The welding position between the coil and the header is set on the outside, which makes it easy to replace the burst heat transfer tube and maintain a stable heat transfer area for the high-pressure heater during long-term operation.

The function of a high-pressure heater is to use steam turbine extraction to heat boiler feedwater, in order to improve the thermal efficiency of the unit. The device consists of two main parts: a shell and a piping system. A steam condensation section is installed at the upper part of the shell cavity, a hydrophobic cooling section is installed at the lower part, and a water inlet and outlet are installed at the top of the inlet and outlet pipes. When the superheated steam enters the shell through the inlet, it can heat the feedwater in the upper main screw tube. After the steam condenses into water, the condensed hot water can also heat part of the feedwater in the lower cooling screw tube. The utilized condensed water is drained out of the body through the drainage outlet. This device has significant advantages such as low energy consumption, compact structure, small footprint, and low material consumption. It can also strictly control the drainage water level, drainage flow rate, and reduce the drainage end difference.

The condenser is an important auxiliary equipment of the steam turbine generator unit. Depending on different conditions, the condenser can use rivers, lakes, seas, or groundwater as cooling water sources. The condenser cooling pipe is prone to corrosion and leakage during operation, which can be caused by excitation forces and thermal loads. Generally, 2-3 major maintenance periods require partial or complete replacement of the cooling pipes.

The TPRT-CY series fine powder separator is an efficient fine powder separator optimized and designed based on the comparative test results of a semi industrial model (Φ 550- Φ 610mm). The unique structural form and reasonable structural parameters and selection enable it to reduce metal consumption while ensuring separation performance - with high efficiency and low resistance, and the layout is very convenient. It can be widely used in the storage type powder production system of large coal-fired boilers.

The coarse powder separator is an important auxiliary equipment in the powder production system, mainly used to roughly separate the coal powder produced by the coal mill. The high-efficiency coarse powder separator has the characteristics of economic practicality, simple and compact structure, easy installation, and convenient maintenance. Mainly used in coal grinding systems, raw material grinding systems, and cement systems in cement plants.

The application of boiler performance optimization software not only brings direct economic benefits to users, but also introduces new system concepts and analysis techniques The goal is to help us break through traditional operating modes, standardize operations, comprehensively improve operational management levels, and achieve better economic benefits.

The boiler air powder online monitoring and control system is developed by the Boiler Combustion Monitoring Technology Research Institute of Xi'an Thermal Power Research Institute. The boiler air powder online monitoring and control system consists of three parts: online monitoring of primary wind speed, online monitoring of coal powder concentration in the primary air duct, and online monitoring of secondary and tertiary wind speeds. Its main function is to guide the boiler to reasonably distribute air and coal, prevent the occurrence of air and powder cuts or pipe blockages, optimize combustion of the boiler, and operate under optimal conditions.

The straight sections of the main air and flue gas pipelines in most power plant boilers are relatively short, and the flue gas pipelines are severely worn, corroded, and clogged. In order to solve this problem, the Thermal Research Institute conducted actual measurements of the pipelines on site based on different boiler conditions. Using measurement methods such as double Venturi and array, measurement devices were designed and installed, achieving good results.
