combustion in a conventional boiler

Maintain stable combustion, which can be achieved in most water-cooled combustion in a conventional boilers with fuel moisture contents as high as 65 percent by weight, as received. Wood fired steam boiler adopts watter-cooling wall shop-membrane structure to improve fuel combustion effect.

Recently, we learned: Rugao City, Jiangsu Province Supervisor Bureau Jiang Security Bureau adhere to safety first, prevention first, the principle of comprehensive management of energy saving, in-depth implementation of combustion in a conventional boiler production, sale, use, import and other aspects of business within the jurisdiction of the main energy saving responsibility inherent jurisdiction to conduct a hazard investigation work boiler.

Inspection process, City Supervisor Bureau Jiang branch of law enforcement personnel to go to boiler units, key to see whether there are coal-fired boilers, boiler inspection whether, whether for the use of registration, whether special equipment operator certificates, boiler safety management system developed and the status of implementation, boiler employees education and training, and emergency rescue drills to conduct audits, establish inspection records and ledger work, to maximize the elimination of security risks.

Up to now, there were still not found the use of coal-fired boiler of Unit within the jurisdiction. City Supervisor Bureau Jiang Security Bureau will continue to work closely with the various departments work together to advance environmental protection and ecological civilization construction work to further strengthen supervision to achieve a comprehensive cleared coal-fired boilers.

Henan gas combustion in a conventional boiler Henan basic components and working principle of gas boiler is constituted by a series of devices can be divided into two main parts and auxiliary equipment. Henan gas boiler main components are: 1. Furnace: Henan ensure the fuel and burn the gas boiler outlet gas temperature to a value of convection heating surface cooled safe work; 2, the drum: the respective gas boiler heating surface coupled Henan and together and water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 3, water wall: mainly radiation heating surface Henan gas boiler absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 4, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion; 5, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reduced exhaust smoke temperature, increase boiler efficiency Henan gas. 6, the furnace wall: Henan protective housing is gas-fired boiler, and heat from the sealing effect. Heavy furnace wall Henan small gas boiler can also function as a support member boiler. 8, the frame: a support member and a fixed gas boiler Henan

Henan run gas combustion in a conventional boiler 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.
