Waste heat boilers are also called waste heat boilers, which use high-temperature exhaust gas generated by various devices to heat water, generate steam or produce hot water (ie steam waste heat boiler, hot water waste heat boiler), and then use the generated steam or hot water to reach waste heat. The purpose of reuse.
The waste heat boiler is an energy-saving and environmental protection project, which reduces the amount of waste discharged, greatly reduces environmental pollution, and at the same time carries out certain recovery of heat.
The boiler that is heated by the high-temperature waste heat that was originally discharged in industrial production can be used for power generation or for supply.
Coal-fired boilers refer to the coal burned by fuel. After the heat of coal is converted, steam is generated or turned into hot water. However, not all of the heat is effectively converted, and some of the heat is not consumed. This has efficiency problems. Generally, the boiler is capitalized. More efficient, between 60-80%. The coal-fired boiler is mainly composed of a main part of the pulverized coal preparation system, the burner, the heating surface, and the air preheater.
Structure type of the boiler body
The type of body structure of a power station boiler depends mainly on factors such as fuel characteristics, boiler capacity and steam parameters. Commonly available are inverted U-shaped, tower-shaped and box-shaped.
The inverted U type is suitable for boilers and fuels of various capacities, so it is widely used. The height of the boiler is lower than other furnace types, and the heating surface is more convenient to arrange. The fan and dust removal equipment can be placed on the ground, but the floor space is large. The boiler body of Figure 1 is an example of an inverted U-shape.
The tower type is suitable for boilers burning with multi-ash bituminous coal and lignite. There is no turning flue, which can reduce the local wear of the fly ash on the heated surface, and the floor space is small. However, the furnace body is high and the installation and maintenance are complicated.
The box type is suitable for large fuel and gas boilers. The flue above the furnace is divided into two parts: one part is directly connected to the furnace exit, and the flue gas flows upward; the other part is flue gas. The advantage is that the structure is compact, the floor space is small, and the connection between the boiler and the steam turbine is convenient. The disadvantage is that the manufacturing process is complicated and difficult to overhaul.
Metallographic Cutting Machine
Easy to set up using an intuitive user interface that requires almost no training
The simple user interface and color display make operation very simple. No complicated menu. Use multi-function knob to set parameters, joystick to quickly position the workpiece, and automatically adjust the height of the cutting wheel. Yes, that's it.
The relocation of the workpiece is replaced by automatic X - axis movement
Thanks to optional X-axis movement, a series of cuts can be performed without wasting time repositioning the workpiece. The cutting table can be moved 40 mm, and the user can choose up to four sliders of different thickness.
With the help of a locator laser, the position can be reached on the first attempt
Positioning can be time-consuming, but Secotom uses a positioning laser to point out where to cut, and positioning becomes a breeze. The combination of laser and joystick enables easy positioning.
Cutting in a variety of sizes and shapes with the ultimate flexibility of the movable T-slot cutting table
Secotom's cutting table provides extreme precision and flexibility for a variety of sizes and shapes. Capable of cutting large and deep workpieces (up to 70 mm/2.8 "in diameter or 165 x 50 mm/6.5" x2 "in size). The cutting table is equipped with 8 mm T-groove, and users can choose from a variety of fixtures that are most suitable for their cutting operations and can achieve the highest accuracy of the toola
