  • What is the application of flue duct boiler expansion joint

    May 11, 2021

    Boiler Expansion Joints Applications on a fossil fuel power boiler are similar to those used on recovery boiler in pulp mill and even those used on HRSG. Even though the operating conditions are similar, the operating systems are different and require different designs. A ducting system can be extensive, and depending on what materials are flowing through, having the right flue duct expansion joint is necessary to prevent leakage, lessen noise and vibrations, maintain operation and safety stands, and reduce the chance of failure. Designed to your specifications and application requirements, we manufactures high quality flue duct expansion joints for industrial ductwork systems.

  • The Function Of Boiler Water Cooled Wall

    May 10, 2021

    The water wall of the furnace is the heating surface arranged around the furnace, and the flowing medium in the tube is generally a two-phase mixture of water or steam and water. If the boiler is a steam boiler, the water wall is mainly an evaporative heating surface; if the boiler is a hot water boiler or a supercritical pressure boiler. Then the water wall is mainly the heating surface. In the natural circulation boiler furnace, if the working fluid in the tube flows upward, the water wall is also called the rising tube. The basic function of the water wall is: ① Absorb the heat of the flame in the furnace. Because the flame temperature in the furnace is high and the smoke velocity is very low, this heat absorption is mainly carried out by radiation, and the temperature of the flue gas is cooled to a sufficiently low degree at the furnace outlet. ②Protect the furnace wall. Due to the existence of the water wall, the flame can only partially or completely not touch the furnace wall, thus playing a protective role. In addition, the water wall can also play a role in suspending the furnace wall and preventing slagging on the furnace wall.

  • CFB Boiler Applications and Its Main Features

    May 08, 2021

    As the mostly used power plant boiler, CFB boiler is widely used for power generation in chemical industry, paper making industry, textile industry, food and drinking industry, pharmaceuticals industry, sugar refinery, tire factory, palm oil factory and alcohol plant, etc. CFB Boiler Main Features 1. Burning efficiency reaches 95%-99%, high burning rate, heat efficiency above 87%. 2. Energy-saving, high efficiency, high flexibility of fuel, which can satisfy the burning of many kinds of fuel. 3. Limestone can be added in bed material during burning process reacts with SO2 of flue formulates sulphate, desulphuration can satisfy environment protection. 4. Reasonable wind distribution and low temperature or furnace can control formulation of NOx and really reach environment protection. 5. Big adjusting range load can be adjusted to 30-110%. 6. High automatic control makes boilers running safely and economically in long term. 7. Adopt upper exhaust high temperature cyclone separated device, high collection of bed material. 8. High heat transfer efficiency, high ability of overload.

  • Economizer For Industrial Boilers

    May 08, 2021

    Industrial boiler economizers have a wide range of applications in industrial production. Industrial boiler economizers are installed behind superheaters or convection tube bundles, which can reduce flue gas temperature, recover flue gas heat, improve boiler thermal efficiency, save fuel, and improve business economy benefit. The working principle of the industrial boiler economizer is to use the heat of the tail flue gas of the boiler to heat the feed water to reduce the exhaust gas temperature of the boiler components. The boiler feed water passes through the economizer to increase the water temperature and reduce the exhaust gas temperature, thereby reducing heat loss. Save fuel and improve boiler efficiency. Industrial boiler economizers, cast iron fin economizers and steel tube economizers are respectively suitable for 2.5MPa and above. Industrial boiler economizers are heat exchange equipment that uses boiler tail gas to preheat boiler feed water. It can effectively reduce the exhaust gas temperature of the boiler, improve the thermal efficiency of the boiler, and save fuel, hence the name.
