Chimney (definition)

Chimney — is a structure designed to remove combustion products (smoke, gas, vapors) from boilers, furnaces or fireplaces to the street, ensuring safe and effective removal of harmful substances from the building. It plays a key role in heating and ventilation systems, preventing the accumulation of harmful gases inside the premises.

Chimney: types

1. Brick chimney:
   • Design: Constructed of bricks, often with an internal lining for improved durability and thermal insulation.
   • Advantages: Durability, high heat capacity, reliability when used with traditional heating systems.
   • Flaws: Long installation time, high cost, need regular maintenance to prevent soot accumulation.
2. Metal pipe:
   • Design: Made of stainless steel or other corrosion-resistant metals. Can be single or double (with an internal heat-insulating layer).
   • Advantages: Quick installation, light weight, corrosion resistance, lower installation costs.
   • Flaws: Lower heat capacity, possibly shorter lifespan than brick chimneys.
3. Ceramic pipe:
   • Design: Made of ceramic pipes, which provide excellent heat resistance and insulation.
   • Advantages: High resistance to high temperature and chemical influences, durability.
   • Flaws: High cost, difficult installation.
4. Sandwich:
   • Design: Consists of two metal tubes with a heat-insulating layer between them. Often used for liquid and gaseous fuel boilers.
   • Advantages: Easy to install, effective thermal insulation, can be installed in limited spaces.
   • Flaws: Lower heat capacity, possible corrosion problems depending on material quality.

Assembly and installation:

1. Design:
   • Needs assessment: Determination of the type of construction depending on the heating equipment used and operating conditions.
   • Calculations: Determination of the diameter, height and angles required for effective removal of flue gases.
2. Preparation:
   • Selecting an installation location: Taking into account distances to structural elements of the building, ensuring safe exit of the chimney to the roof or outside the building.
   • Preparing the base: Brick and ceramic smoke exhaust may require the construction of a foundation or base.
3. Installation:
   • Brick chimneys: Construction of smoke exhaust in accordance with the design, laying of bricks and mortar, installation of internal cladding.
   • Metal and sandwich chimneys: Installation of pipes and fittings, compliance with the manufacturer's instructions for assembly and installation.
   • Ceramic chimneys: Installation of ceramic pipes, ensuring tightness of connections.
4. Check and launch:
   • Checking for leaks: Make sure there are no leaks and the pipe is functioning efficiently.
   • Commissioning works: Checking the operation of the system to ensure safe and proper removal of combustion products.
5. Service:
   • Regular cleaning: Clears away soot and deposits to prevent fire hazards and ensure efficient operation.
   • Checking the status: Regular inspection for cracks, corrosion or other damage.

Smoke exhaust structures play a critical role in maintaining safety and efficiency. heating systems, and their proper installation and maintenance are key to ensuring reliable operation of the heating system.
