The Introduction Of Water Wall 2023-02-01
Bare tube type water wall is composed of ordinary smooth seamless tubes; Membrane water wall is welded on the light tube or directly tied fins, the top of the fins of each tube welded together, the whole water wall is connected as a whole; The pin type water wall is welded on the water wall with many long small round steel as nails, which is mostly used to lay the combustion belt, so that the refractory material can be hung on the pipe. Light tube type water wall is usually used in small capacity medium and low pressure boilers, film type water wall and pin type water wall are usually used in large capacity high temperature and high pressure boilers.
Three Types Of Air Preheater 2022-12-08
The air preheater can be regarded as a heat transfer equipment, which can achieve high efficiency heat exchange performance and reduce energy consumption loss. Its main role is to help fuel combustion to play the latent heat. We all know that there are losses in the heat transfer process, and the high energy loss of equipment performance is poor. The heat transfer efficiency is related to the structure and heat transfer mode of the equipment. According to the structure, the air preheater can be divided into plate type air preheater, tube type air preheater and rotary type air preheater. 1. Plate air preheater is made of a plurality of thin steel plates and formed into a rectangular plate bundle by welding. An air preheater is composed of a plurality of plate bundles.

The general industry is called "anti-wear tile", "anti-wear cover plate". Tube shields is a special boiler accessories, generally used in power plant boilers, small boilers are used less, some coal chemical industry will also be used. The production process of tube shileds is the use of high pressure press, professional mold pressing, short production time, good welding performance, welding should not fall off, smooth surface, beautiful appearance. The curved tube shields is formed by pressing on the press or bending with a special mold on the pipe bender.
Expansion Joints Compensator For Boilers Parts 2022-11-17
Expansion joint is also called compensator, expansion joint (device). It is an indispensable and important link in modern pipeline engineering system. Applicable to all walks of life, as long as there is a pipeline where there is an expansion joint, such as: petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy, steel mills, construction, pharmaceutical, heating, municipal engineering, natural gas and so on. The function of expansion joint in the pipe system in shutdown and startup two different states, due to temperature changes, the pipe will cause thermal expansion or cold contraction. If these expansions and contractions are not compensated (eliminated or balanced), they can cause serious damage to the system and prevent it from working properly.

How to choose good quality boiler tube pipes? 2022-10-24
While choosing boiler tubes, pick out the right and good quality tube according to following steps: Look at the cross-section of the tube. A good quality seamless tube will have a smooth cross-section and will be devoid of bumps and irregularities. Check the density of the pipe to understand the percentage of impurities in the pipe. If the pipe shows low density, steer clear! Check the surface of the boiler tube. A good quality boiler tube will have a smooth surface. If you find the surface to be rough and uneven, you can be sure that the quality is not up to the mark.

Chain Grate Boilers 2022-05-13
Chain grate is the most widely used mechanized combustion equipment in industrial boilers, but it has a certain range of coal types. The combustion method of the chain grate is a moving fire bed combustion, and the fuel ignition condition is "limited ignition". The fuel enters the grate through the stoker. With the movement of the grate, the combustion process begins in the furnace, and the burnt slag is discharged to the slag well at the end of the grate with the movement of the grate. Therefore, compared with reciprocating furnace, vibrating furnace and boiling furnace, chain grate has higher requirements on coal grade. The mechanical coal throwing furnace is basically a layer-fired grate with infinite fire, and the adaptability to the coal quality is relatively wide.

The Reheater For Power Plant Boilers 2022-02-18
The reheater is essentially a steam superheater that reheats the low-pressure steam that has done work and reaches a certain temperature. The function of the reheater further improves the thermal efficiency of the power plant cycle and enables the steam temperature of the last stage of the turbine to be controlled. within the allowable range. The reheater is the heater in the boiler that heats the steam from the steam turbine into superheated steam. There are two functions of the reheater: one is to reduce the humidity of water vapor, which is beneficial to protect the turbine blades; the other is to improve the relative internal efficiency and absolute internal efficiency of the steam turbine. The layout of the reheater follows the layout of the superheater, and there are three types: convection, radiation and semi-radiant. Convective reheater has countercurrent, cocurrent, mixed flow, single tube ring, double tube ring, multi-tube ring, in-line, staggered, vertical, horizontal, parallel to the front wall, perpendicular to the front wall. Convective reheaters are reheaters that primarily absorb convective heat. Radiant reheater refers to a reheater that absorbs radiation from the furnace. Semi-radiant reheater (that is, screen superheater) refers to a reheater that absorbs more radiation in the furnace (radiation heat absorption exceeds 1/2 of the total heat). The material selection principle of the reheater is the same as that of the superheater. Since the cooling capacity of the reheated steam is lower than that of the superheated steam, the design wall temperature of the superheater is generally higher than that of the same temperature grade. The metal pipes of the high temperature reheater are generally made of alloy steel (metal with a total alloying element exceeding 5%) pipes. For example, 12CrlMoV, steel 102, SA213
What is an Economizer? 2022-02-14
An economiser is a mechanical device which is used as a heat exchanger by preheating a fluid to reduce energy consumption. In a steam boiler, it is a heat ex-changer device that heats up fluids or recovers residual heat from the combustion product i.e. flue gases in thermal power plant before being released through the chimney. Flue gases are the combustion exhaust gases produced at power plants consist of mostly nitrogen, carbon dioxide, water vapor, soot carbon monoxide etc.
Air Preheater For Power Plant Boilers 2021-12-29
Air preheater (air preheater), also referred to as air heater, is a kind of preheating equipment that improves the heat exchange performance of the boiler and reduces heat loss. The function of the air preheater is to transfer the heat carried in the flue gas discharged from the flue at the tail of the boiler to the air before entering the boiler through the radiating fins to preheat the air to a certain temperature. The air preheater rotates slowly during operation, the flue gas will enter the flue gas side of the air preheater and then be discharged, and the heat carried in the flue gas will be absorbed by the heat sink in the air preheater, and then the air preheater The heat sink rotates slowly, the radiating fin moves to the air side, and then transfers the heat to the air before entering the boiler. The application of air preheater in boiler is mostly three-division bin type, with fire alarm system, gap adjustment system and frequency conversion control system attached. The air preheater is easy to use, simple to operate, safe to operate, and can improve the heat exchange performance of the boiler system, so it is widely used in the flue gas boiler system. The air preheater is a device that collects and utilizes the waste heat of flue gas. The application of air preheater can directly reduce the temperature of boiler exhaust gas and reduce the heat energy loss in the system. At the same time, the radiating fins of the air preheater can absorb and conduct heat energy, which is equivalent to increasing the heating surface of the boiler and improving the thermal efficiency of the boiler. The air preheater has the function of heating the air required for the fuel in the boiler. The use of the air preheater can improve the combustion conditions of high-temperature air and reduce the heat loss caused by incomplete combustion of the fuel. The application of air preheater can also increase the temperature in the furnace, increase the level of radiant heat transfer and
