Product Description

Coal Fired Steam Boiler description icon

SZL series coal fired steam boiler is a new type of water tube assembled boiler independently developed by Fangkuai and integrating the advantages of bulk boiler arches. It cleverly applies the water-cooled arch technology and membrane water wall technology of the combustion system of large chain grate boilers to assembled boilers. The boiler is mainly composed of upper and lower drums, convection tube bundles, water-cooled wall tubes, downcomers, and headers. The upper and lower drums are arranged vertically. The combustion equipment adopts a chain-belt chain grate and is driven by a stepless transmission device. The boiler body consists of vertical upper and lower drums and convection tube bundles. Water-cooled walls are arranged around the combustion chamber, and the front and rear arches are made of water-cooled walls as the skeleton is poured with refractory castables, so the service life of the furnace arch is longer. The left and right sides of the main body are full-membrane water-cooled wall structures, the boiler is well sealed, and the heat dissipation loss is small, ensuring the safe and efficient operation of the boiler.

Product Advantages

Coal Fired Steam Boiler advantages icon
  • Safe & Stable

    The discharge of the safety valve has been strictly calculated. When the system pressure exceeds the specified value, the safety valve will automatically open to release the pressure to ensure the safe operation of the boiler.

  • Full combustion

    Different numbers of independent air bins are set according to the tonnage of the boiler, and the air distribution can be adjusted according to the combustion situation to ensure that the fuel is fully burned.

  • Easy installation and maintenance

    The platform escalator is fixed by bolts and nuts, and the upper and lower drums are equipped with manholes, which are easy to open and easy to clean. The furnace is equipped with an inspection door for easy inspection and maintenance.

  • Anti-corrosion

    Formed by cold rolling and compression molding, the concave-convex panel has good rigidity and is lightweight. And the surface is coated with primer and topcoat after de-rusting treatment, and the anti-corrosion effect is good.

Technical Features

  • Heat exchange system

    A coal fired steam boiler typically uses a heat exchange system consisting of several components. The combustion chamber is where coal is burned to generate heat. The heat is then transferred to the heat exchange surfaces. Heat exchange surfaces are the surfaces that come into contact with the hot gases produced by the combustion of coal. The heat exchange surfaces may include the boiler tubes, water walls, and superheaters. The hot gases transfer heat to these surfaces, which then transfer the heat to the water. The water circulation system in a coal-fired steam boiler typically consists of pumps, piping, and drums. The steam drum is a large vessel located above the boiler. It collects and stores the steam generated by the heat exchange system. The superheater is a heat exchange surface that is used to increase the temperature of the steam. The steam is passed through the superheater after it leaves the steam drum. The superheater transfers additional heat to the steam, increasing its temperature and energy.

  • Intelligent Control System

    The coal-fired steam boiler adopts a multi-level authority design to facilitate the operation and management of the water heater. High-resolution color touch screen, dynamic graphic interface, clear operating data, and easy operation. Historical data and historical fault query; automatic combustion adjustment to ensure the stability of the outlet water temperature of the water heater and reduce the number of burners starts and stops. Automatic fault identification, analog instruments, bar graph visual indication, and processing. Data analysis and curve display detection parameters, smoke exhaust Temperature detection function, and historical alarm record query are convenient. There are descriptions of touch screen operation, maintenance, troubleshooting, and other related information in the window, which is convenient for beginners Quickly familiarize yourself with the operation and application of the control system.
