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.
