Tips for using factory chimneys mainly include the following aspects:
Enhance chimney suction power:
Use induced draft fan: induced draft fan can provide stable and adjustable suction power, which is not affected by weather and air pressure changes. It is like a "little helper" of the chimney, which can help solve the problem of smoke backflow, and is not picky about the location and can be used anywhere it is needed.
Chimney diameter change: By using a diameter change device, the chimney diameter can be enlarged. When used with an induced draft fan, the suction power of the chimney can be effectively improved, solving the problem of insufficient suction power of the side chimney.
Chimney effect and suction principle:
Chimney effect: This is to use the air density difference formed by the temperature difference between the inside and outside of the building to make the smoke and hot air flow convect in the vertical space, thereby enhancing the suction power of the chimney. The chimney effect of high-rise buildings is particularly obvious. The hot air generated by the furnace rises rapidly when it is working, and the bottom air is quickly drawn in, so the fire is more intense.
Anti-corrosion treatment of chimneys:
Preliminary preparation: Clean the dust, oil and other debris on the inner and outer walls of the chimney, check and repair cracks and damage. Choose high temperature and corrosion resistant coatings and sealants.
Construction process: Spray anti-corrosion coating evenly on the inner wall of the chimney, apply waterproof coating on the outer wall, and consider applying glass fiber reinforced materials. Pay attention to the control of temperature and humidity during construction to ensure uniform coating and detailed treatment of the construction surface.
Post-maintenance: Regularly check the inner and outer walls of the chimney, repair damaged or corroded parts in time, entrust professional companies to carry out maintenance inspections, and introduce intelligent monitoring systems for real-time monitoring and early warning.
Safety measures:
Construction safety: Safety regulations must be strictly implemented during construction to ensure the safety of construction personnel. Suspension operators must undergo physical examinations and safety technical training, and factors such as wind and humidity must be controlled during construction.
