Natural gas boilers use one of two types of burners, atmospheric burner (natural suction) and compressed air burner (forced air) or electric burner. Nox burners (the type of nitrogen oxides most associated with air pollution) and pre-mix burners (burners where air and gas are mixed before the fan) are commonly used to reduce air loss and stabilize air quality. And even required in some areas. To ensure the usefulness of mixing the air and fuel entering the burner, these types of burners can reduce NOx leakage.

The best ways to maintain and operate a boiler start with maintaining a regular schedule of reviewing reports and checklists to ensure proper equipment operation. Pressure, water temperature, and vent gas temperature reports should be recorded daily so that they can be used as a basic reference for troubleshooting system performance. More detailed checks and checks should be important to provide system performance. Without this, there may be gradual changes in system performance over time that are not clearly visible. Tips for achieving performance efficiency include, for example, daily, weekly, and monthly inspection reports that you can apply to the building. The following maintenance checklist is provided based on the methods used in this article.

Steel boilers, as their name implies, are made of steel and are usually made of horizontal cylinders. Steel boilers have a combustion chamber in which pipes are placed around this chamber. The pipes that are installed around the combustion chamber of steel boilers are made of a special alloy so that they do not burn or damage in the face of a direct flame. These pipes are called (fire pipes). Steel boilers are divided into friends from the point of view of heat transfer, which are as follows.

The hot water produced by the boiler is pumped through pipes and reaches the building equipment, which can include hot water coils in the fan coils, hot water heating equipment and heating systems. Boilers produce steam that flows from high-pressure to low-pressure areas through pipes without the need for an external energy source, such as a pump. The steam used for heating can be used directly for steam-powered equipment, or through a heat exchanger can generate heat to produce hot water for the equipment.

Cast iron boilers that are cross-sectionally cast iron are another type of engine room boiler that is used to heat commercial premises. These boilers do not use pipes, but instead, have cast-iron sections with water and combustion gas corridors. The cast iron parts are screwed together and look like a steam radiator. These parts are connected to each other by fireproof washers. These boilers are used to produce steam or hot water and are available in sizes from , to , BTU.
