The turbine follow-up control mode refers to the control system automatically adjusting the control parameters of the turbine based on the detected load changes, in order to achieve load follow-up control. This control mode can maintain the stable operation of the turbine while improving its thermal efficiency and operating life.
Load changes are inevitable in a turbine power plant. In order to ensure the stable operation and safety of the power generation system, a follow-up control mode is ad...
The forced draft fan and induced draft fan are two critical components of an industrial boiler that work together to maintain proper airflow and control the combustion process. The interlocking system between these fans is designed to ensure safe and efficient operation.
The interlocking system includes sensors and controls that monitor the airflow and pressure in the boiler. If there is a malfunction or issue with either the forced draft fan or the induced draft fan, the interlocking system wi...
The primary reason for a boiler to undergo spraying is to protect its surfaces from corrosion, scaling, and fouling caused by high-temperature and high-pressure steam. This is done by applying a protective layer of material onto the boiler's inner surfaces, which helps to prevent the accumulation of deposits and minimize the risk of equipment failure. Spraying is a crucial process in boiler maintenance, as it ensures that the boiler remains in optimal condition, improves its lifespan, and mainta...
The purpose of boiler pipe flushing is to use the self-generated steam of boiler to flush away the rust, welding slag, iron filings, ash scale and oil scale and other impurities in the superheater, reheater heating surface pipe and steam pipeline, otherwise the following hazards will occur when supplying steam to the steam turbine:
(1) The high-speed steam flow carries sundries and impacts the turbine blades, forming a large number of pits, which will cause the blades to break in severe...
With the strengthening of the awareness of cultivated land protection, the state has issued a policy of prohibiting the production of clay solid bricks all over the country, and some enterprises that produce and process clay solid bricks have gradually transformed and started to produce new wall building materials-aerated concrete, whose production cost and quality are much better than those of clay solid bricks. Therefore, aerated concrete blocks have become the development direction of new bui...
The thermal efficiency of boiler refers to the percentage of effective heat in the heat delivered by fuel. The thermal efficiency of boiler is one of the important indexes to reflect the energy efficiency of boiler. Many users often ask, what is the general thermal efficiency of natural gas boilers? In this page, ZOZEN Boiler will analyze the thermal efficiency of natural gas boiler and introduce the calculation method of thermal efficiency.
What is the general thermal efficiency of nat...
Circulating fluidized bed boiler (CFB) is a fluidized combustion boiler. Its main structure includes combustion chamber and circulating furnace. It has many advantages such as high thermal efficiency and low pollution, and is especially suitable for inferior coal. During use, all parts of the boiler are playing their respective roles. Here, we will focus on the function of the separator of circulating fluidized bed boiler.
The working principle of circulating fluidized bed boiler separa...
Chain furnace is a kind of mechanized combustion boiler equipment which is widely used in industrial boilers. It is mainly used in drying, disinfection, sterilization, distillation and other technological links, and is widely used in many industries such as food, paper, construction, cable, electronics, tobacco, textile and so on. However, many users are not very clear about what chain furnace is.
Chain furnace is a boiler using chain grate as combustion equipment. The working principle...
