Abstract

The invention discloses an automatic rotational lifting monitoring system for fouling and slagging of a boiler furnace of a coal-fired power plant. The system comprises a fixing support, a lifting platform, an imaging system, a cooling device, a driving mechanism and a displayer, wherein the lifting platform is matched with the fixing support in a sliding mode, the imaging system is installed on the lifting platform and comprises a charge coupled device (CCD) camera and an optical lens, the cooling device is fixedly sleeved outside the optical lens, an observation port which is matched with the optical lens is arranged at the bottom of the cooling device, the driving mechanism is used for driving the imaging system to rotate, and the displayer is connected with the imaging system. The system is convenient to use, flexible to lift and rotate, safe, reliable, high in economical efficiency and capable of integrating visualization, rotating and lifting functions and achieving the effect that the condition of the heating surface of the furnace can be monitored in a multi-angle and all-round mode through a single camera.

Description

technical field [0001] The invention relates to the field of monitoring the thickness of ash deposits and slagging in coal-fired power plant boilers, in particular to an automatic rotating and lifting monitoring system for ash deposits and slagging in furnace chambers of coal-fired power plant boilers. Background technique [0002] Mineral and inorganic components in coal become coal ash after being burned in the furnace. When the flue gas flow passes through the heating surface, these coal ash and other non-combustible substances are slowly deposited together, causing the contamination of the heating surface. Contamination phenomena fall into two categories: slagging and ash deposition. [0003] The so-called slagging refers to the accumulation of melted ash deposits on the heated surface wall, which is related to the composition, melting temperature, viscosity and wall temperature of some ash particles that migrate to the wall surface due to various forces. , mostly occu...
