The water level of steam drum can reflect the condition between feedwater quantity and evaporation quantity of boiler. If the two parameters maintain a stable balance, the water level also remains unchanged; otherwise, the water level will rise or fall. Besides, there is also a false water level phenomenon. How do we understand the false water level?
Flue gas flow rate in industrial boilers refers to the rate or volume at which flue gas flows inside the boiler. The calculation of flue gas flow rate is used to understand the combustion state and thermal efficiency of industrial boilers for optimization and improvement purposes.
The calculation of flue gas flow rate usually takes into account factors such as the temperature and pressure of the flue gas, the density of the flue gas, and the flow rate of the flue gas. The main purposes of calcu...
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...
