Hot water boiler control system applying PLC controller

Abstract

The invention discloses a hot water boiler control system applying a PLC controller. The hot water boiler control system comprises the PLC controller, a fuel monitoring module, a fuel addition module,a water supply module, a flue gas treatment module, a boiler, a wireless communication module, a human-machine interaction module, an audible and visual alarm, a display module and an input module; the fuel monitoring module monitors a temperature in a boiler furnace in real time, when the temperature in the boiler furnace is monitored to be higher or lower, the audible and visual alarm generatesan audible and visual alarm, and transmits monitored data to the PLC controller. If a temperature value in a boiler drops, fuel is about to be exhausted, at this time, the PLC controller controls thefuel addition module in time to perform fuel delivery, and a feed control module performs quantitative filling control on the fuel to avoid insufficient combustion caused by too much filler, therebyavoiding adding materials manually, and improving the combustion rate and the heat stabilization effect of the boiler fuel.

[0002] Hot water boilers include electric hot water boilers, fuel-fired hot water boilers, gas-fired hot water boilers, and coal-fired hot water boilers. Hot water boilers are boilers that produce hot water. , solar energy, etc.) is a kind of thermal energy equipment that heats water to the rated temperature, hot water boiler, the water inlet and outlet are connected from the top of the upper drum, and the water inlet distribution pipe guides the water inlet to the downpipe to enter the front and side lower headers, through The water-cooled wall pipe is heated and rises; the front and rear ends of the upper drum are provided with water baffles at the boundary between the descending and ascending water flows, and the water baffles only cut off the lower half of the drum; for forced circulation, the water inlet is connected The lower header at the front end rises from the front water-cooled wall tube to the upper drum, then transfers to the side water-cooled wall tube and descends the tube to the side lower header, and then enters the side water-cooled wall tube to rise to the upper drum. The hot water boiler circulates and insulates through the hot water circulation pump The hot water in the water tank is heated repeatedly to achieve the purpose of bathing; the hot water boiler circulates the hot water in the heating pipe through the hot water circulation pump, and can meet the heating requirements of people through the radiator; the hot water boiler and the hot water circulation The pump cooperates with the heat exchanger to realize the dual functions of bathing and heating. The combustion stability and combustion efficiency of the boiler will affect the production cost and the heating rate of the boiler. The control functions of the existing boilers are mostly focused on the startup, Stop, the function is too simple, and adding fuel manually to control the combustion temperature does not allow the boiler workers to know the temperature parameters in the boiler in time, and cannot adjust the combustion in time, resulting in a low combustion rate and stability rate of the boiler fuel. For this reason, Propose a hot water boiler control system using PLC controller
