Design: A simple vertical boiler is a type of boiler that features a vertical cylindrical shell with a firebox at the bottom and a flue at the top. The heat generated by the fuel combustion rises through the flue tubes, heating the water surrounding them.

Heat Output: The heat output capacity of 250,000 kcal/h indicates the amount of heat energy the boiler can generate per hour. This capacity is suitable for various applications, such as small-scale industrial processes, heating systems in commercial buildings, or specific heating requirements in certain settings.

Fuel Type: Simple vertical boilers can be designed to run on different fuel sources, including solid fuels (e.g., coal, biomass) or liquid fuels (e.g., oil, gas). The specific fuel type depends on the boiler design and the requirements of the application.

Compact Size: Simple vertical boilers are known for their compact size, making them suitable for installations with limited space. They can be easily installed in small industrial settings or commercial facilities.

Limited Pressure Capacity: Vertical boilers typically operate at lower pressures compared to larger industrial boilers. The pressure range depends on the design and intended application, but they are generally considered to be low to medium-pressure boilers.

Basic Controls: Simple vertical boilers often feature basic controls for operation, temperature regulation, and safety measures. These controls may include manual or automatic fuel feeding mechanisms, draft controls, pressure and temperature gauges, and safety valves.

It's worth noting that specific design variations and additional features may be present in different models or manufacturers of simple vertical boilers. It's important to consult with boiler manufacturers or experienced professionals to determine the suitability of a particular boiler for your specific application and to ensure compliance with safety standards and regulations.
