properties of boiler plant

Conventional low nitrogen low nitrogen gas properties of boiler plant combustion technology mainly focus on how to reduce the combustion temperature to reduce the thermal nitrogen oxides (NOx) generated carried out, the main techniques include staged combustion, premixed combustion, flue gas recirculation. 1, a fuel staged combustion / combustion air staging thermal NOx amount largely depends on the level of the combustion temperature. In the equivalent ratio of the combustion temperature reached the highest value in the case 1, the combustion under lean or rich combustion cases, the combustion temperature will fall much. Using this principle to launch a staged combustion technology.

How to choose the properties of boiler plant manufacturers? Boiler is an apparatus for energy conversion, or by various chemical energy efficient power boiler input energy to the boiler capable of outputting high temperature water and steam and organic heat, hot water can be provided, and producing power for everyone. The boiler manufacturer is a professional research and production of various boiler business, if companies want to purchase boiler should choose a high quality and reliable boiler manufacturers.

Henan run gas properties of boiler plant Q & A (III) 1. Henan boiler water wall type of gas main, which has several? A: (1) a tubular water-cooled wall light; (2) membrane wall; (3) water-cooled wall inner walls of the helical groove; (4) a pin-type water-cooled wall (also called stab waterwall tubes). Such water wall surface of the light pipe is required over a certain length of the welding bar, and to facilitate the laying of refractory material is fixed. Mainly used a slagging combustor zone, and certain solid slagging cyclone furnace 2 furnace. Henan role bullnose gas boiler are those? A: (1) increasing the length of the horizontal flue. Because the bullnose is extending into the furnace equivalent to an increase of the horizontal flue bullnose length. Thus, it is possible without increasing the depth of the boiler, the arrangement of the superheater heating surface more. (2) improve the heat transfer effect of the platen superheater. The flue gas from the vertical to the platen superheater in the absence of the bullnose, lateral erosion, erosion to the landscape, increased convective heat transfer effect. (3) increase the flue gas in the furnace so that the fullness of the flue gas distribution in the height direction of the combustion chamber tends to be uniform. Increasing the furnace so that an upper water-cooled wall and roof before the superheater heat absorption. 3. How to structure the bottom of the steam heating apparatus, Henan gas boiler? A: The device is placed along the length of the lower header tank steel in the second line, opened on the pipe holes 5mm diameter (number of holes corresponding to the number of the water wall) and connected to the steam pipe introducing foreign when administered with, intake air is controlled by a valve. 4. ? Principle Henan natural gas-fired boiler circulation is like A: Steel furnace in the cold state, full of inner drum water level elevation below the water evaporation system is stationary. When the tube is heated in the boiler rises, part of the water vapor is generated, forming a mixture of a less dense soda. While the heated downcomer outside the furnace. Water denser tube. In this way both the density difference effect arises impetus, soda mixture flows upward in the water wall, after the header, the catheter into the drum, the downcomer from the drum to the flow of water downwardly through the second line added to the water wall tank, so that the continuous circular flow. The formation of a natural cycle. 5. What is the circulation rate in Henan gas boiler? A: The amount of water entering the recycle loop and the riser G ratio D of the amount of steam at the outlet of the riser pipe is called the cycle rate. 6. The main fault Henan natural gas-fired boiler circulation are those? A: The main fault of the natural circulation circulation stagnation, back, soft drinks stratification, down pipe with gas and boiling heat transfer deterioration. 7. Henan gas boiler water circulation back at what happens? What's the harm? A: The water cycle back phenomenon occurred in the riser direct introduction of steam drum water space, as well as its weight when heated weak pressure differential is greater than the common circuit and the tube. When the vapor bubbles back up the tube with water down flow velocity close, the bubble will not be taken away, stagnant or slow moving state of bubbles increases gradually gathered, vapor-lock is formed, this temperature rise or wall alternating wall temperature, or over-temperature resulting in fatigue failure.

Major scientific and technological innovation is the State of the weighing, State of the weapon must be firmly in their hands, we must rely on self-reliance and independent innovation. - Xi Jinping December 14, kicked off at the Third International Fair of Innovation and Entrepreneurship Center at the National Convention. As China's first international "double hit" Expo theme show to the world maker culture: power generation, focusing on innovation! Fast Boiler Co., Ltd., Henan Province, to participate as an outstanding representative of the exhibition, at the provincial delegation of the booth, the party fast low nitrogen product model properties of boiler plant and remote monitoring system is placed at the front, leaders at all levels attach great importance to the domestic foreign passengers .

Coal Bottom Ash/Boiler Slag - Material Description - User

Ordinarily, boiler slags have a smooth surface texture, but if gases are trapped in the slag as it is tapped from the furnace, the quenched slag will become somewhat vesicular or porous. Boiler slag from the burning of lignite or subbituminous coal tends to be more porous than that of the eastern bituminous coals.

Selecting Coal for use in Boilers based on Characteristics

Bituminous coal is commonly used in power plant boilers for generation of electric power. Bituminous coal has a higher boiler heating value than either sub-bituminous or lignite, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest and Appalachian regions. Plant chemists conduct analyses of the coal as it is received.

Basic Layout and Working of a Thermal Power Plant

Boiler: The mixture of pulverized coal and air (usually preheated air) is taken into boiler and then burnt in the combustion zone. On ignition of fuel a large fireball is formed at the center of the boiler and large amount of heat energy is radiated from it. The heat energy is utilized to convert the water into steam at high temperature and pressure.
