Embodiment Construction

[0038] The biomass boiler applicable to this embodiment includes a combustion chamber, an induced draft fan, a blower, a star feeder, a star feeder, a steam drum, a water pump, a grate machine, and a slag remover. Among them, the combustion chamber is also called the furnace, which is the place where biomass particles are burned; the induced draft fan draws air to the outside of the combustion chamber to generate negative pressure in the combustion chamber; the blower delivers air to the combustion chamber; the star feeder adds biomass particles to the combustion chamber ; The steam drum stores water and water vapor; the water pump delivers water to the steam drum; the grate machine and the slag remover are used for slag removal.

[0039] Such as figure 1 As shown, the control system of this embodiment includes various sensors, a program controller and a control cabinet. Among them, the control cabinet is used to install the program controller, the corresponding power supply ...

Abstract

The invention discloses a biomass boiler control system. The system comprises a combustion chamber gas pressure sensor, a steam-pocket steam pressure sensor, a steam-pocket water level sensor and a program controller; and the program controller comprises a processing module, a storage module, a combustion chamber gas pressure sensing signal input module, a steam-pocket steam pressure sensing signal input module, a steam-pocket water level sensing signal input module, a combustion chamber gas pressure adjusting signal output module, a steam-pocket steam pressure adjusting signal output module and a steam-pocket water level adjusting signal output module. The automatic control of a biomass boiler is realized by the use of various sensors and the program controller. In particular, full combustion of biomass granules is ensured, the utilization rate of fuels is improved and the energy is saved by step control of different steam-pocket steam pressures; and in addition, alarm and emergency blowout treatment under various hazardous conditions are realized and safe production is ensured by the monitoring of the sensors.

Description

technical field [0001] The present invention relates to a boiler equipment, more specifically, the present invention relates to a biomass boiler control system. Background technique [0002] Biomass energy is the solar energy stored in plants due to photosynthesis of plants. It is estimated that the annual energy stored in plants is equivalent to 10 times the world's main fuel consumption, while the utilization of energy as energy is less than 1% of the total. At present, countries all over the world, especially developed countries, are devoting themselves to the development of high-efficiency and non-polluting biomass energy utilization technologies to protect mineral resources, ensure energy security, and realize CO 2 Reduce emissions and promote sustainable economic and social development. [0003] Biomass boiler is an important way to utilize biomass energy. The boiler control system is an extremely important link in all parts of the boiler equipment. The control sys...
