Main Difference Between EN12952-15:2003 and Other Boiler Performance Test Standard
Due to the different standard systems in different countries, there are some differences in the boiler performance acceptance test standards or procedures such as European Union standard EN 12952-15:2003, ASME PTC4-1998, GB10184-1988 and DLTT964-2005. This paper focuses on the analysis and discus...Read more -
Development Of Low-speed CFB Boiler
Low-speed CFB Boiler features a clean combustion technology with high efficiency, less energy and low pollution emission. Low-speed CFB Boiler Characteristics 1) Since the boiler has separator and refeeder, the furnace contains a large amount of heat storage materials. These circulated materials ...Read more -
Boiler Drum Structure
Boiler Drum is the most important equipment in boiler equipment, and plays a connecting role. When water becomes qualified superheated steam in a boiler, it has to go through three processes: heating, vaporization and overheating. Heating from feed water to saturated water is a heating process. V...Read more -
Heat Recovery Steam Generator Structure and Process
Heat Recovery Steam Generator (HRSG for short) recovers heat from gas turbine waste gas by steam. The gas out of gas turbine has a temperature of 600C. These high-temperature gases enter waste heat boiler to heat water into steam to drive steam turbine to generate electricity. The generating capa...Read more -
Steam Boiler Principle
Steam boiler principle is very easy to understand, and the model diagram below includes riser, steam drum and downcomer. The riser is a cluster of dense pipes, which is connected by upper and lower header. The upper header connects to steam drum through steam introduction pipe, and steam drum con...Read more -

CFB Boiler Coking Preventive Measures
CFB boiler coking will increase rapidly once occurs, and the coke lump will grow faster and faster. Therefore, prevention of CFB boiler coking and early detection and removal of coking are the principles that operators must master. 1. Ensure good fluidization condition and prevent bed material de...Read more -
Boiler Slagging Hazard
Boiler Slagging Hazard is very serious and dangerous. This passage will discuss the boiler slagging hazard in the following several aspects. 1. Boiler slagging will cause overhigh steam temperature. When a large area of furnace is coking, the heat absorption will be greatly reduced, and the flue ...Read more -
Cause of Boiler Slagging
Boiler Slagging has many causes, and the most important ones are as follows. 1. The impact from coal type The cause of boiler slagging has a direct relationship with coal type. If coal is of poor quality and large ash content, it is easy to form coking. 2. The impact from pulverized coal quality ...Read more
