The hidden arm type coal powder sampling device, also known as the rotary arm type coal powder sampling device, is a specialized equipment for sampling coal powder on the primary air supply pipeline of a positive pressure direct fired coal powder system. It is an accurate control and analysis of coal powder fineness in power plant coal-fired boilers, and is very important for the safe and economic operation of boiler units

The water vapor sampling device is used for online chemical analysis, measurement, and network monitoring of water vapor quality in thermal systems of thermal power plants, secondary loop systems of nuclear power plants, etc. Various analytical instruments are centrally arranged on the instrument rack and can be manually sampled. Provide over temperature, over pressure, and cut-off protection for the sample water entering the instrument, and set up a cooling water cut-off protection system to ensure the safe and reliable operation of the instrument.

The rotary push coal powder sampling device is a specialized equipment for sampling coal powder on the primary air supply pipeline of a positive pressure direct blowing coal powder system. In the daily operation of the coal mill, the wear of the grinding parts, changes in coal type and block size, and significant changes in coal powder fineness will directly affect the combustion efficiency of the boiler and increase power generation costs. Therefore, regular sampling and testing of coal powder fineness is necessary. When the coal powder fineness exceeds the design value, the grinding parts of the coal mill should be adjusted or replaced in a timely manner, or the opening of the separator should be adjusted to achieve the design requirements for coal powder fineness.

The coal powder sampling device is used for regular coal powder sampling on the primary air coal powder pipeline of the powder production system. Due to the wear of the grinding parts of the coal mill, changes in coal type and block size, the fineness of coal powder will undergo significant changes and directly affect the efficiency of boiler combustion. Therefore, it is necessary to regularly sample and test the fineness of coal powder. When the fineness of coal powder exceeds the design value, it is necessary to adjust the opening of the separator disassembly door in a timely manner, or adjust and replace the grinding parts of the coal mill.

Sampling coolers are used for cooling of steam and water analysis samples in boiler rooms or power plants, such as steam analysis sampling, boiler water analysis sampling, and deaerator effluent analysis sampling. At present, the sampling coolers produced by our company generally adopt a serpentine tube surface cooling structure. Special requirements can be made to use plate heat.

Turbine oil vacuum oil filter is mainly used for oil filtration in power plants, power stations, substations, electrical manufacturing plants, paper mills, electrochemical plants, and industrial and mining enterprises. Suitable for filtering water, gas, and impurities in turbine oil, insulation oil, refrigeration oil, and mechanical oil below grade 30.

Rotating the filter screen once is an important filtering and cleaning equipment in the primary circulating water system of thermal power plants. Due to the increase of pollutants in rivers, lakes, and seas in recent years, the safety of water intake is seriously threatened. The rotating primary filter produced by Lianyungang Huaneng Power can effectively intercept and remove suspended and floating particles in the water flow, such as aquatic plants, leaves, branches, fish and shrimp, white plastic pollutants, industrial, agricultural and household waste, etc., ensuring the safety and economic operation of the power plant.

A pipeline cleaner (also known as a filter or drain) is a device used to remove impurities, particulate matter, suspended solids, and other pollutants from pipeline systems. It is widely used in water treatment, HVAC, industrial circulating water systems, petrochemicals, and other fields. Its core function is to protect downstream equipment (such as water pumps, valves, heat exchangers, etc.) from impurity damage and ensure stable system operation.

Basket filter, also known as drum filter, is a new type of filtration equipment designed and manufactured by Lianyungang Huaneng. It is a small device that removes a small amount of solid particles from liquids. It mainly consists of a connecting pipe, a main pipe, a filter blue, a flange, a flange cover, and fasteners.

The bag filter has a filtration accuracy of 1-200 microns, which can be chosen by customers. Different precision filter bags can also be replaced at any time to meet the different requirements of customers at different times. The bag filter has a compact structure, reasonable size, simple and convenient installation and operation, and occupies a small area.

It is used for filtering water in cooling water systems and other water pipelines in industries such as thermal power plants, hydropower stations, steel smelting, petrochemicals, printing and dyeing, and papermaking. It has the characteristics of interception and discharge, and is an advanced and reasonably priced cleaning and filtering device.

The secondary filter screen is one of the main equipment in the circulating water system of the condenser. It is used to filter the cooling water, remove impurities that may block the tube plate and cooling pipe in the water flow, and ensure the normal operation of heat exchange equipment such as the condenser and its rubber ball cleaning device. When the cooling water is mixed with debris and passes through the system, the debris is blocked by the small hole filter on the upstream surface of the filter. After being purified through the small hole, the cooling water enters the condenser and is backwashed by the backwashing device and the drain valve in the filter. The water flow flows in the opposite direction, and the debris stuck on the inlet surface is backwashed out of the mesh by the water flow and led out by the drain valve. As long as the purification filter keeps working, the cooling water entering the condenser will always be clean, and the resistance of the filter will not increase.
