The boiler chimney is a type of commercial chimney used for the emission of combustion exhaust gases from boilers. Boiler chimney design not only affects the operational efficiency of the boiler but also concerns environmental protection and equipment safety. To ensure efficient exhaust and long-term stability of the boiler chimney system, attention needs to be paid to various aspects such as structural design, material selection, and safety.
The design of the boiler chimney must first ensure smooth discharge of exhaust gases. The height, diameter, and overall structure of the chimney must comply with boiler atmospheric pollutant emission standards. According to relevant regulations, the height of the chimney should meet the requirements of boiler atmospheric pollutant emission standards to ensure that exhaust gases are effectively discharged and reduce pollution to the surrounding environment. If, for special reasons, the height of the chimney cannot meet the requirements, it must be approved by local environmental departments and measures such as improving dust removal efficiency and increasing draft must be taken to ensure emissions meet environmental requirements.
Additionally, boiler chimney design should ensure sufficient strength and rigidity to prevent structural deformation or damage during operation.
The lining material of the boiler chimney needs to be high-temperature resistant and have good anti-corrosion properties to withstand the erosion of high-temperature exhaust gases. The chimney should be lined with heat-resistant materials, and steel plate chimneys must conform to a series of design requirements.
Boiler chimney design requirements include ensuring the chimney has sufficient strength and rigidity to withstand the high temperatures and pressures generated during boiler operation. For chimneys with a height-to-diameter ratio exceeding 20 times, reliable guy wires must be installed, arranged circularly and evenly in 3 to 4 strands to enhance structural stability. The connection part between the chimney and the foundation should preferably be conical, and the foundation should be made of concrete, to enhance wind and earthquake resistance.
The safety of the boiler chimney is the most critical part of the design. Boiler chimney design in structure must ensure that it can operate stably under extreme conditions such as high temperature and strong winds. Additionally, the inner and outer walls of the chimney should be painted with high-temperature-resistant and anti-corrosion coatings to enhance corrosion resistance and avoid structural damage caused by long-term high temperatures. Oil and gas boilers should use reinforced concrete or steel chimneys to improve structural safety and durability. The chimney must be able to withstand the thermal load of the boiler system, while avoiding stress concentration caused by thermal expansion.
Boiler chimney design is not only related to the exhaust efficiency of the boiler but also to the safety of operation and environmental protection. Choosing a high-quality, high-safety boiler chimney system is the foundation to ensure the efficient and safe operation of the boiler.
