In China, Class D boilers refer to steam boilers with a rated working pressure of 1.0 MPa and a rated evaporation capacity of 2 tons/hour or less. These boilers are typically used in small to medium-sized industrial facilities, such as food processing plants, chemical plants, and textile mills.
Class D boilers are subject to certain safety and performance requirements, including compliance with national and industry standards for design, manufacturing, and operation. These standards are...
Biomass boilers do produce emissions when they burn organic materials such as wood chips, pellets, or agricultural waste. The exact type and amount of emissions depend on various factors such as the type of fuel used, combustion efficiency, and air pollution control technologies in place. However, with proper design and operation, biomass boilers can emit significantly less pollutants than traditional fossil fuel boilers, making them a more environmentally friendly option for heat and power...
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...
