  • 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...

  • 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...

  • 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...

  • 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 ...

  • 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 ...

  • What Is Boiler Coking

    Boiler Coking is the accumulated block formed by local fuel accumulation at burner nozzle, fuel bed or heating surface. It is common for coal fired boiler or oil boiler, under the circumstance of high temperature and less oxygen. In general, the ash particles are cooled together with the flue gas...

  • Design of Gas Condensing Boiler

    Gas condensing boiler is a steam boiler that condenses the vapor in the flue gas into water by condenser. It recovers the latent heat released during condensation process, and reuses such heat to achieve 100% or above thermal efficiency. The flue gas temperature of conventional gas fired boilers ...
