Brick chimneys, as a traditional and reliable way of building, still have a place in the construction market. This article will detail the whole process of new brick chimney, including the process flow, precautions and practical application cases.
The process of building a brick chimney
1.First of all, it is necessary to design the chimney according to the actual situation of the plant, such as the emission of flue gas, temperature and pressure. Factors such as fire resistance, compressive resistance and thermal expansion coefficient of bricks need to be considered in the design.
2.Choose refractory bricks, cement, sand and other auxiliary materials of acceptable quality. Ensure that the size, shape and appearance of the bricks meet the relevant national standards.
3.According to the design drawings, the foundation pit was excavated, and a concrete cushion was laid. Make sure the foundation is solid enough to support the weight of the entire chimney.
4.In order from bottom to top, the chimneys are built layer by layer. Each layer of bricks should be coated with appropriate cement mortar, and the brick joints should be tight and neat.
5.During the masonry process, the inside of the chimney is waterproofed, anti-corrosion and fire-proof. This includes the application of refractory materials, the installation of corrosion protection facilities, and the installation of thermal insulation, among other things.
6.After the masonry is completed, a comprehensive quality check is carried out, and performance tests such as pressure tests and emission tests are carried out. Ensure that the chimney meets the design requirements and is safe to use.
Precautions and Practices
1.Consider the effects of local climatic, geological, and hydrological conditions on the chimney. For example, active areas require special attention to the seismic performance of chimneys.
2.Ensure that safety measures are in place during construction, such as wearing safety helmets, using seat belts, etc. At the same time, it is necessary to pay attention to the health of workers and prevent occupational diseases caused by long-term exposure to dust.
3.Establish a strict quality management system to ensure that every link meets national and industry standards. This includes strict control of materials, supervision of the construction process and final acceptance testing.
