Detailed description of the invention
As it is shown in figure 1, biomass gasification steam boiler controls system by drum pressure module, vaporizer thermal module, blower module and what air inducing module formed.Drum pressure module, including drum pressure sensor, drum pressure actuator and feed frequency regulator and air blast frequency regulator；Vaporizer thermal module, including vaporizer temperature sensor, thermoregulator and feed frequency regulator；Blower module, including zirconia sensor, zirconium oxide actuator and air blast frequency regulator；Air inducing module, including B/P EGR Back Pressure Transducer EGR, draft regulator and air inducing frequency regulator.Wherein, drum pressure sensor is arranged on boiler-steam dome top, and chamber temperature sensor is arranged in vaporizer upper end, and zirconia sensor is arranged in vaporizer upper end, and combustion chamber draft sensor arranges upper end in a combustion chamber.
Drum pressure module: being the input being connected drum pressure actuator by drum pressure sensor signal outfan, pressure regulator outfan divides two-way to connect feed frequency regulator and the input of air blast frequency regulator respectively.Wherein, drum pressure sensor is arranged on boiler-steam dome top.Pressure regulator arranges drum pressure setting value and receives the signal of telecommunication of drum pressure sensor, both export after computing relatively again, output signal divide two-way be delivered separately to feed frequency regulator and air blast frequency regulator, pressure regulator output signal is for adapting to load fluctuation size adjustment needs, having played complementary effect.
Vaporizer thermal module: be the input being connected vaporizer thermoregulator by vaporizer temperature sensor signal outfan.Wherein, vaporizer temperature sensor is arranged in vaporizer upper end.The setting value of the thermoregulator of vaporizer, is divided into three parts according to the requirement of vaporizer temperature, i.e. ceiling temperature, medium temperature and lower limit temperature.In medium temperature, performing feed output preset frequency, when vaporizer temperature reduces from medium temperature, system is by automatically going out how many feeding coals burning required for the temperature reduced from theory analysis, namely on a predetermined basis plus corresponding frequencies output；When vaporizer temperature raises from medium temperature, system by automatically can from theory analysis go out raise temperature required for how many feeding coals burning, namely deduct on a predetermined basis corresponding frequencies output.Signal is obtained after fire box temperature actuator conversion data by vaporizer temperature sensor, and be analyzed comparing with interim temperature value, ceiling temperature value and lower-limit temperature value, it is input to feed frequency regulator to process, and after outputting signals to the common calculation process of feed frequency regulator with pressure regulator, send corresponding signal to batcher, perform corresponding feeding coal.
This feed regulates system and adopts double Mode Control feeding coal, i.e. drum pressure module and gasification room temperature module, can reach to ensure that gasification furnace gasification temperature can regulate gasification size according to payload again in time, reach combustion purpose.
Blower module: connected zirconium oxide actuator input by zirconium oxide oxygen content sensor output.Wherein, zirconia sensor is arranged in vaporizer upper end.Zirconium oxide actuator sets setting value and receives the oxygen content signal of oxygen analyser, after com-parison and analysis, air blast frequency regulator is arrived in output, and after outputting signals to the common calculation process of air blast frequency regulator with pressure regulator, send corresponding signal to aerator, reach combustion gasification purpose.Wherein, another road exports the input of air inducing frequency regulator, feedovers as air inducing frequency regulator, i.e. the situation of change of air blast size can be timely fed back to air inducing frequency regulator and calculate.It is exactly that the air output making boiler is coordinated mutually with fuel quantity that zirconium oxide regulates the task of system, oxygen content in air, data are detected by oxygen analyser, these data are delivered in numeral Fuzzy Controller and be analyzed, correctly regulate air output, make fuel gas fully be gasified, make the best air output of its Step wise approximation actual condition simultaneously, the most high thermal efficiency of boiler can be reached, it is achieved economical combustion.
