This type of pot or boiler is made up of connecting cast iron pieces called fins. Due to the ability to assemble and disassemble the cast iron boiler, it can be used in spaces where it is not possible to use a steel and integrated boiler. In fact, cast iron boilers are assembled and installed in the engine room. types of sections are used in the construction of each capacity of cast iron boilers, which are as follows.

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.

The presence of large amounts of accumulation of insoluble solids (TDS) in the boiler water can cause sedimentation and reduce the efficiency of the boiler. Therefore, it is necessary to keep the number of solids below the specified limit. As the total hardness increases, the likelihood of sedimentation and sedimentation increases. Drainage of water, called pot immersion, requires the removal of some of the undissolved solids and keeping the total hardness below the rate at which it precipitates. Low but constant and frequent submergence of high doses but rarely is better because it preserves energy, water, and chemicals. Large boilers with a constant load must be continuously submerged where small amounts of water are constantly drawn from the boiler and fresh compensation water is produced.

Cast iron boilers are very useful because they can be collected in the basement and passed through smaller doors and gates. The most important drawback is that they are prone to leakage due to the connection of the parts by the washer when the washer becomes old or damaged by chemical reactions. Among the famous cast iron boilers in Iran, we can mention the boiler cast iron boiler and M.I. cast iron boiler made by Iran Pipe and Machine Building Company.

Ventilation gas savings provide the best heat recovery opportunity. In boiler chimneys, there is a need for heat exchangers to transfer heat from the flue gas to the return water or to feed the boiler or combustion air. They even work well in boilers and operate at relatively low flue gas temperatures. There is a large room to recover some of the flue gas heat, which rises if the flue is not recovered. Saving gas from the chimney usually increases the overall efficiency of the boiler by to percent.
