Hot Air boiler Control System
Introduction of the Hot Air Boiler Control System
This control system is suitable for coal-fired hot air boilers,with automatic and manual boiler control functions such as temperature control,air volume control, fuel feeding control,and slag remover control.In addition to the above functions,the control system can also monitor the real-time data of the analog quantity on site,and some basic interlocked and alarm functions.
HMI: 7-inch color touch screen,which can display the operating conditions of the boiler and conduct man-machine dialogue operations.
The core of the hot air boiler control system adopts Siemens programmable controller S7-200smart.
Which brand is PLC?
We adopt Siemens SIMATIC S7-200 SMART,which has high performance,high integration,and is more simple.Combined with Siemens SINAMICS drive products and SIMATIC human-machine interface products,the small automation solution with S7-200 SMART as the core will create more value for customers.
What are the features of the PLC?
Introduction of hot air boiler
The hot air boiler is a thermal power machine,which has become a heat source.There are many varieties and complete series of hot air boiler,which are divided into coal,oil,gas stoves,etc. according to the type of fuel.According to the customer's equipment technology and parameters,our self-developed hot air boiler PLC control system,realizing operation intelligent.
Working Principle of the Hot Air Boiler
The furnace is equipped with energy-saving front and rear arches,and the rear of the furnace is equipped with a whirlwind combustion chamber,which can ensure full combustion of fuel and low heat loss.The principle is that the coal is sent into the furnace through the grate,the fan blows air,passes through the coal seam, and fully burns with the coal on the chain to generate high-temperature flue gas.The high-temperature flame enters the secondary combustion chamber and the cyclone burnout chamber to burn again,so that the hot air Furnace flue gas blackness is lower than "Lingelmann 1".The chain grate energy-saving hot air boiler has stable heat supply,high degree of automation, high efficiency and environmental protection,and is safe and reliable.
