high pressure water tube boiler

Fangkuai Boiler is based on low-nitrogen energy-saving and environmental protection. It focuses on the development trend and uses universal excellent technology, products and services. According to such a method, it is now applicable to the development of society around the world, promotes cutting-edge work in the future manufacturing industry, and maintains the ideal use of customers in various industries.

A scale-up of the technology to 100 MW is investigated in terms of mass and heat balances,flows,solids inventories,high pressure water tube boiler dimensions and the major differences between a full-scale Circulating Fluidized Bed boiler.Furthermore, the additional cost of 100MW CFB power plant boiler relative to CFB technology is analysed.The largest cost is made up of compression of CO2,which is common to all capture technologies. Although the need for oxygen to manage incomplete conversion is estimated to be only a tenth of that of oxy-fuel combustion,oxygen production is nonetheless the second largest cost.Other significant costs include oxygen-carrier material, increased boiler cost and steam for fluidization of the fuel reactor.

Hot water high pressure water tube boilers are mainly used for heating and bathing. The hot water of the water tank can be heated by circulating hot water circulation pump and the hot water of the tank is heated again and again, which can realize the goal of bathing. The hot water circulation pump circulates the hot water of the heating pipe, and the radiator (radiator) can meet the requirement of people's heating, and the hot water boiler and the hot water circulation pump cooperate with the heat exchanger can realize the double functions of bath and heating. In the natural circulation hot water boiler, the inlet and outlet water are piped from the top of the pot. By the water intake pipe, the inlet water drop pipe is guided into the front and side of the header, and heated up through the water cold wall tube. Before the drum, the back end is down and up The riser boundary is provided with a water barrier, and only the lower part of the drum is cut off. For forced circulation, the inlet water is connected to the front lower header, the front water wall pipe rises to the top of the drum (when the front water wall drop pipe is cancelled), and then it is transferred to the side water wall drop pipe to the side bottom header, and then the side water wall pipe is put up to the up drum. From the front of the convection tube down to the down drum, finally, the bottom of the pot between several torches of water from the back of the pot.

Wall Wall maintenance position on an inner wall of the high pressure water tube boiler furnace, the evaporator heating surface is made up of many parallel tubes thereof. Wall played a role in the operation of the boiler when the heat is absorbed by the boiler flue gas hearth radiation, after absorption to produce steam or hot water in parallel with the pipe, so it can reduce the temperature in the furnace, meaning play to protect the furnace. Case generated in the boiler inside the large-capacity, high-temperature flame in the boiler furnace or heat radiation more, so that the boiler furnace water wall can absorb more than 45% of the generated heat. In the present water-tube boiler, the water wall to make the evaporation more heating surface. When overhaul of the water wall if ignored, we can not find slagging problems, so that the device does not work. When it works, if the temperature exceeds the absorption capacity of its own, it will lead to pipeline explosions, sometimes also makes boiler burst, we can see that we have the relevant maintenance work into total overhaul want with among the issues. 1.3 overhaul the so-called superheater superheater, meaning its existence it is to deal with steam. After the superheated steam into the steam turbine, a superheater if there is a problem such that the heat will drop, and thus cause the device to water vapor with problems affecting the blade so that the device can not be safely run. If the steam temperature is higher compared to the normal, so that the blade will heat up, leading to shortened time of the device used, affect the service life. 2 main factors affecting the safe operation of the boiler

High Pressure Boilers: Features and Advantages ~ ME

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
