Embodiment Construction

[0009] Depend on figure 1 It is known that the movable titanium sponge resistance furnace includes an inner furnace cover 5 and an outer furnace cover 1. The inner furnace cover is a hollow structure, and a sponge titanium fiber lining 4 is arranged between the outer wall of the inner furnace cover and the inner wall of the outer furnace cover. The sponge titanium fiber The furnace lining 4 is prefabricated into a circular frame 5, on which a support rod 6 is welded, and the end of the support rod is covered with a refractory ceramic tube, and the heating element is suspended on the refractory ceramic tube, and is heated by radiation heating. Heating bricks 7 are laid on the hearth, and the heating bricks are spliced ​​and combined to form circular arc bricks. The difference between the outer arc radius and the inner arc radius of the arc bricks is 5-30 cm. The number of the concentric rings 2-6, and the distance between each concentric ring is 3-20 centimeters. The heating b...

Abstract

The invention relates to a mobile titanium sponge resistance furnace comprising an inner furnace cover, a coil base and an outer furnace cover. The inner furnace cover is of a hollow structure, a titanium sponge fiber furnace lining which is prefabricated into a circular frame is arranged between the outer wall of the inner furnace cover and the inner wall of the outer furnace cover, and a support rod is welded on the frame. The mobile titanium sponge resistance furnace is characterized in that a fireproof ceramic tube is sleeved at the end of the support rod, a heating part is hung on the fireproof ceramic tube, and a radiation heating mode is adopted for heating. By the mobile titanium sponge resistance furnace, heating surfaces can be increased, heating space can be reduced, furnace temperature uniformity is improved remarkably, heating rate is increased greatly, electric energy is saved, heating elements disposed at the furnace bottom can be increased as many as possible with load bearing guaranteed, bottom heating condition of workpieces is improved greatly, and accordingly overall uniformity in heating of the workpieces is improved.

Description

technical field [0001] The invention relates to a large-scale power station boiler, in particular to a movable titanium sponge resistance furnace. Background technique [0002] With the progress of the times, modern large-scale power plant boilers are developing in the direction of large capacity and high parameters. However, with the improvement of boiler parameters, the heat load of the furnace section is increasing, and the possibility of coking of the water wall of the furnace increases accordingly, which seriously affects the economy and safety of boiler operation, causing the unit to sometimes have to limit the load or even shut down. If serious coke loss occurs, it will also endanger the safety of the unit operators. However, the current use rate of sponge titanium resistance furnaces in my country is low, and they have not been able to fully play their role. Finding out the problem and solving it is our country's solution to blowing The primary issue of ashes quality....
