Collective Flue Pipes of Apartment Heating Systems and Features of their Arrangement

One of the many types of building heating systems is the apartment heating system, which provides for the arrangement of a separate apartment heating system with an autonomous heat generator in multi-stored residential buildings. This heat generator can work both on fossil (gas, liquid and solid heating) heating, as well as on electric and renewable energy. Installation of such heating systems in Georgia started just 20-25 years ago, after centralized heat supply systems were completely dismantled. Currently, wall-mounted boilers with a closed combustion chamber powered by natural gas are used as heat generators in apartment heating systems, which, along with individual apartment heating, also provide hot water preparation for domestic purposes. Such systems are cheaper, independent and easily adjustable. Almost all buildings equipped with an apartment heating system are left without a structural element necessary for such systems, a chimney, which leads to multiple penetration of combustion products into the apartments. For apartment heating systems, it is necessary to arrange collective flue pipes, which will release emissions from heat generators located on one vertical into the environment, above the building. The article discusses the main schemes of the collective systems for the removal of combustion products and the peculiarities of their arrangement. Dimensions of flue and air ducts for heat generators of different thermal power used in apartment heating systems are given.
