Description
Technical Field
The invention belongs to the technical field of furnace tube oxide skin cleaning, and particularly relates to a crawling microwave oscillation oxide skin cleaning system.
Background
The ferrite and austenite tubes widely used in the boiler high-temperature section furnace tube can generate an oxide layer on the inner wall of the furnace tube under the action of steam when the tubes run at high temperature, can block further reaction between iron and water or steam, and can prevent corrosion of certain components in the medium in the tube to metals. However, under certain conditions, the oxide layers can be separated from the base material, and the peeling of a large amount of oxide layers is extremely harmful to the running safety of the unit.
At present, the problem that oxide skin falls off commonly exists in supercritical (super) critical parameter boilers in China, and a large amount of oxide skin falls off in supercritical (super) critical parameter boilers which are operated for a long period and a high load.
After the oxide skin on the heating surface in the tube is removed, the oxide skin is accumulated on the lower elbow and the horizontal section of the furnace tube. When the one-time falling accumulation amount is large, the through-flow section of the pipe is completely or mostly blocked, the steam flow is blocked, and the pipe is exploded due to instantaneous overtemperature and overheating in a short time; when the oxide scale accumulation amount is small, a small part of the through-flow section of the pipe is plugged, so that the boiler pipe is subjected to long-term chronic overheating pipe explosion.
And the oxide skin solid generated in the boiler heating surface is brought out by steam and enters the steam turbine, and is accelerated by the regulating valve and the nozzle, so that the turbine blade is corroded, eroded and abraded, the molded lines of the valve, the blade and the nozzle are changed, the surface roughness and the gap of the valve, the blade and the nozzle are increased, the efficiency of the steam turbine is obviously reduced, and the maintenance cost of a unit is increased. If the oxide skin deposits between steam turbine main valve case and disk seat, cause the main valve bite when the unit shut down easily, unable normal shut down threatens the safe operation of unit. The scale cinder that gets into in the steam turbine is carried by steam and is flowed together, and at the start-up stage of unit, the various hydrophobic states that are in of steam turbine, therefore the scale cinder can get into hydrophobic, steam extraction system along with steam, after the dilatation of step-down, when the velocity of flow descends to the degree that can't carry the scale cinder, the scale cinder begins the deposit to block up tiny pipeline, drain valve, check valve etc. easily.
The oxide skin is peeled off and also can influence the soda quality of unit, and behind the machine side, the oxide skin granule itself diminishes, becomes garrulous, enters into condensate system from the low pressure jar, and the adhesion leads to secondary pollution at water wall pipe, height heater water side again, has the potential safety hazard to unit normal operating.
