Guide plate wear technology principle

Circulating Fluidized Bed Boiler Abrasion boiler personnel have thorny problems in order to reduce boiler water wall wear and water cooling wall baffle plate grinding technology and layered load-bearing wall anti-wear air deflectors, thereby effectively relieving the material Flow erosion attached to the cooling water wall (link http://), belt, reduce the flow rate of the material to change the flow direction of the material, the high-speed impact of the separation of the water wall and material flow, reduce the material particles on the water wall cutting losses, Fundamentally solve the problem of water wall tube wear. In order to bring the well-being from the unplanned shut-down inspection circulating fluidized bed boiler into good condition, the technology caused by the boiler's deformation of the water wall tube boiler is safe for continuous operation of the combustion, reasonable after installation, and use the same to achieve Anti-wear effect.

The new grinding process features anti-guide plate 1, the installation period is short and easy to install. Take 240 tons of boilers, for example, only 3 days during construction. New technologies have been used in many home appliance factories. Practices in operation show that the wear of the water wall is obviously reduced after the guide plate is installed, the water wall tube is not more than 0.1 mm, and the casting material, especially in the transition zone, is no longer using any other anti-wear measures.
2. The anti-abrasion technology of the guide plate is to relieve the particulate material in the furnace, so that the anti-wear technology of the guide plate used in the draft cycle is a high-temperature and wear-resistant alloy casting. The maximum temperature can be increased. At 1250°C, the tensile strength is greater than or equal to 560 mpa. The material has a good anti-abrasive technology for the circulating fluidized bed boiler water-cooled wall, from the material that guarantees the use of life for more than 6 years.
3, Water-based cotton clothing flow swirl angle cooling wall contact wear principle is to change the material surface flow and hole vortex of the four-corner material particles, raw material flow tends to center, water wall and collision avoidance.
4, anti-wear guide plate is mainly installed in the furnace in the dense phase area around, because it is a kind of metal material, the heat transfer can be improved in a certain role, so there will not be any negative effect on the load capacity of the boiler.
5, The drainage plate can effectively break the flow of the uneven wall material of the vortex tube formed by the vortex, and reduce the collision between the material particles and the water wall.
In order to avoid the wear of the water wall tube on the solid material, the function of the water wall is protected.
6, around the furnace installed in the wear-resistant baffles, can effectively reduce the speed along the water-cooled wall tube, isolated material flow and water wall tube contact material particles, which fundamentally solved the water wall tube wear.
