Daily maintenance of the cooler

2025-06-09

Excellent coolers are a type of heat exchange equipment used to cool fluids. Usually, water or air is used as a coolant to remove heat. There are wall mounted coolers, spray coolers, jacket coolers, and serpentine coolers. The PTFE cooler used for low temperature in power plants is a new type of equipment for waste heat recovery in power plants to reduce exhaust gas temperature. The use of fluoroplastic heat exchangers can prevent acid corrosion an...

Application of detachable spiral plate heat exchanger

2025-06-09

Detachable spiral plate heat exchangers are widely used. In China, spiral plate heat exchangers have been used to replace shell and tube heat exchangers in the conversion heat exchangers and lower heat exchangers of small and medium-sized synthetic ammonia plants. The equipment cost for using spiral plate heat exchangers for electrolyte heaters and concentrated alkali coolers in caustic soda plants is only one-third of that of shell and tube heat e...

Introduction to air preheaters

2025-06-09

Air preheater is generally referred to as an air preheater. Mostly used for coal-fired power plant boilers. It can be divided into two types: tube box type and rotary type, among which rotary type is further divided into wind cover rotary type and heating surface rotary type. Power plant boilers commonly use heating surface rotary preheaters. The application in boilers is generally divided into two compartments, three compartments, and four compart...

Principle of vacuum rake dryer equipment

2025-06-09

The vacuum rake dryer is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction, and a scraper stirrer is used to continuously remove the materials on the hot surface, forming a circulating flow in the container. After the water evaporates, it is pumped out by a vacuum pump. Vacuum rake dryer is widely used in organic semi-finished products and fuel drying operations in the chemical industry. The ...

Advantages of spiral fin tube technology

2025-06-09

1. Long service life, more than three times that of wrapped welded finned steel pipes. 2. The root of the fin forms an arc cut with the tube, and the surface of the fin is smooth, completely eliminating the accumulation, blockage, and slagging phenomena caused by the folding of the fin root in other forms of finned tubes. 3. The use of hot rolling technology in production has improved the density, yield strength, tensile strength, and wear resi...
