Vibrator control method for biomass gasification power generation system

Abstract

The invention discloses a vibrator control method of a biomass gasification power generation system. The biomass gasification power generation system comprises a reactor, wherein the reactor comprisesa cracking chamber, a combustion chamber, a reduction chamber, a vibrator and a heat preservation shell. The system is characterized in that the vibrator in the reactor is controlled by monitoring the pressure and temperature parameters of the combustion chamber and reduction chamber and the property parameters of fed materials, running of the vibrator is controlled by means of a specific equation, and the internal pressure, temperature and material property parameters of the reactor are shown as Rratio=Pc / Pr*ed / m*(Tc-Tr), wherein Rratio represents a reaction completion degree indicating parameter of the reactor, Pc represents the pressure of the combustion chamber, Pr represents the pressure of the reduction chamber, e represents a natural constant, d represents an average particle sizeparameter of the materials, m represents a water content parameter of the materials, Tc represents the temperature of the combustion chamber, and Tr represents the temperature of the reduction chamber. When Tc is greater than or equal to 900 DEG C, the vibrator is controlled to carry out following actions according to Rratio: (1) when Rratio is greater than or equal to 20 and smaller than or equalto 80, the vibrator continuously vibrates for 30 seconds every 5 minutes; (2) when Rratio is smaller than 20 or greater than 80, the vibrator vibrates continuously for 3 minutes every 5 minutes.

Description

technical field [0001] The invention belongs to the technical field of biomass gasification power generation, in particular to a vibrator control method for a biomass gasification power generation system. Background technique [0002] Biomass is the fourth largest energy resource after coal, oil, and natural gas. It is an environmentally friendly renewable resource, accounting for 14% of the world's total energy consumption. In order to fully develop biomass energy and improve my country's energy structure, the state promulgated and implemented the "Renewable Energy Law" in 2006 to encourage and support the development and utilization of renewable energy, and provide a series of financial subsidies for renewable energy development and utilization projects. Tax incentives. [0003] Jiangsu Province is the province with the largest number of biomass power plants in my country. According to the survey, since the country promulgated and implemented the "Renewable Energy Law" in...
