Thermal power plant is the use of wear resistant ceramic parts
Thermal power plant unit can be divided into the boiler, turbine, power generation of three parts.Our product is widely applied in coal-fired power plant.
> > > coal conveying system Raw coal conveying process is as follows:
The coal yard - reclaimer's delivery - level transport the coal to multistage stand to pulverized coal bin, coal feeder to raw coal bucket, coal mill.
Conveying coal coal conveying system, operation process, the raw coal can cause serious impact to the equipment.Cannot adopt ceramic piece, therefore, be sure to use wear-resistant ceramic plate with rubber lining.Otherwise, will run under a massive loss.
This part of the proposal to choose our company for the development of a coal conveying system of adhesive and impact resistant wear resistant ceramic liner, it has the following advantages:
> AL2O3 ceramics with 95% added a variety of unique formula of wear-resisting material, 100 tons of dry pressing molding, has high density, toughness, wear resistance, etc.By the detection of the Shanghai institute of ceramics, my company production of wear-resistant ceramic wear resistance is equivalent to 266 times of manganese steel and 171.5 times of high chromium cast iron.
> my company ceramic unique spherical design, can effectively buffer material transform plate impact, avoid the material broken ceramic piece, after 10 years of application, won widespread praise users.
> high quality rubber elastic rubber, effectively buffer material impact on wear-resistant ceramic liner.
> viscose department our company for wear resistant ceramic plate paste design, can make the adhesion of rubber and metal N2.5 > 120.
According to the characteristics of the different parts of a coal conveying system suggest choose different products do wear lining:
> dou turbine cylinder can choose wear-resisting ceramic lining board;
> multistage coal station coal bucket can choose wear-resisting lining board, wear-resisting lining, wear-resistant ceramic lining;
> pulverized coal bin and coal scuttle, the polyvinyl alcohol polymer materials widely used these parts before, but the effect is not very good, easy to fall off (because is bolted), can according to the size of the gap between wear-resisting lining board, the effect is very good;
> > > the coal pulverizing system
According to different coal pulverizing system has a different design.
1. The low speed ball mill pulverizing is intermediate storage system)
The working principle of low speed ball grinding powder systems:
Coal mill outlet - wood (chip) separator (have a mesh screen, light physical isolation effect, some have powder tube into round back.)To coarse powder separator, fine powder separator to pulverized coal bin, row powder storehouse to bend - time, three times in elbow to burner, boiler body.
Products in the following parts can be used:
Under the export of coal mill, coarse/fine powder separator cone, coarse/fine powder separator exports, row spiral case of powder, powder tube, the level of the wind and the breeze elbow.
2. The medium-speed coal mill:
This kind of coal mill is more, different structure, but belong to straight waft powder, mainly is part of the coal mill wall.
Medium-speed coal mill of inner cone hopper, outlet pipe and pulverized coal pipe can choose wear-resisting ceramic liner.
In addition to the above mentioned equipment, power plant, some parts can be directly use my company's products, such as ceramic liner, ceramic steel, steel pipe, ceramic lined steel pipe, ceramic lined composite steel pipe, elbow, tee, ceramic hopper, ceramic pipe, ceramic coal measures, coal drop pipe, ceramic rubber lining board, ceramic composite lining rubber plates, rubber lining, these products are of national standard, also has the mark, can also be customized according to customer's requirements, it is very convenient to use and replacement.
