Qualified Brown Coal Hot Water Szl Boiler

Qualified Brown Coal Hot Water Szl Boiler

Coal-fired qualified brown coal hot water szl boilers to gas-fired boiler and the basic requirements of a program, the transformation of the basic requirements: 1, the boiler must be carried out in accordance with "Steam Boiler Safety Technology Supervision" and "Hot Water Boiler Safety Technology Supervision" and relevant national technical regulations, construction program should be sent to the local technical supervision departments for approval. 2, to determine the value in use based on the transformation of the boiler has the age and state of the art, taking into account the life expectancy of the boiler. If the boiler use a longer useful life, and the pressure there is a serious corrosion, scaling and overheating phenomena such elements, no transformation of value. 3, boiler walls, chimneys, water supply and air supply, the wind system should remain largely intact. 4, after the transformation of the original technical parameters should be kept constant boiler (operating pressure, temperature, etc.) or the load and to improve the efficiency of the original boiler. 5, after the boiler should comply with national environmental and technical indicators, solve the problem of smoke and dust, meet environmental requirements. 6, when the boiler should try not to change the original pot, and the body is pressed by the original system architecture, covers the smaller the better. 7, rehabilitation programs should be simple, low investment, short construction period and quick, safe and reliable. Second, the transformation method: 1, removal of the original coal-fired boiler slag machine, equipment on coal, dust, chain grate and gearbox. 2, according to the diameter and length of the flame, furnace installation height determining geometric dimensions and the burner. 3, making the furnace, the furnace bottom refractory brick, a semicircular shape. 4, the front arch openings mounted burner nozzle. 5, after that the flame away from the center position of the tube the arch, the arch of the pipe on the basis of the original slope, heightening baffle wall, the protective tube arch. 6, install blast doors. 7, install the induced draft fan drive. 8, the body of the boiler water test pressure 1.5 times the working pressure. 9, the automatic control system installed. Third, the technical proposal: 1, furnace design should consider the flame length and diameter of the flame of the combustion gas, so that the furnace space is filled with the best of the flame, the flame not Wall flush. 2, as the main component of natural gas CH4, H20 generated after combustion, steam share large, so that strong radiation, heating furnace suitably increased to take advantage of the radiation heat transfer, thermal efficiency, reduce the consumption of steel, ensure that the boiler output, and may increase the boiler output. 3, a slight positive pressure within the boiler furnace using a combustion or slightly negative pressure, the sealing performance of the boiler furnace walls to strengthen, not air leakage. 4, due to the smaller excess air ratio of the gas boiler, combustion requires less air flow, coupled with the removal of dust, dust and small flue system, the flue resistance is reduced, a large surplus primer fan flow, using file when the damper plate adjusting the power loss is large, frequency control can be induced draft fan air volume regulation. 5, after the furnace door and see the fire smoke chamber above the chimney, mounted two proof doors, in order to improve the antiknock performance of the boiler. 6, the boiler flue gas the volume of gas in the vapor component is generally 15% to 19%, well above the coal-fired boiler flue gases generated in the water vapor content of 6% by volume or less. Boiler shutdown and startup, due to the low wall temperature of the boiler heating element, when less than less 50 ℃, the flue gas water vapor dew condensation on the wall will, if not removed condensate with the condensate of the contact wall would be C02 acid gas corrosion of furnace wall and the insulation material due to water absorption and thermal insulation effect will be lost. Therefore, before and after the gas hot water boiler smoke box and the rear box and the rear flue smoke condensate discharge means to be provided, promptly boiler condensate removal. 7, the gas boiler-system control function should have combustion process. Pre-blowing may be implemented, auto-ignition, flame detector self-test, automatic load adjustment, flame monitoring, fault alarm interlock shutdown, the gas leak detection valve, induced draft fan and burner control sequential chain protection. 8, in order to prevent fluctuations in the gas pressure regulator to meet the burner requirements, the installation of a gas regulator metering panel outer gas inlet in the boiler room, the surge counter can be accomplished by filtration, regulating, metering, safety shut-off functions.

PolockGroup Group was founded in 1999, is a famous comprehensive enterprise in Bangladesh, covering many types of machinery, textile, paper and other production and processing equipment. Whether mechanical manufacturing, textile processing or paper products can not do without the help of steam qualified brown coal hot water szl boilers. High quality steam can not only provide mechanical support for producing power; also meet the textile, paper processing disinfection process needs a number of drying, rinsing and the like. The performance of a steam boiler are very good in general can bring qualitative leap for the production.

Boiler qualified brown coal hot water szl boiler should be classified according to which of several energy conversion device is a way, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Many types of boilers, we like how to categorize them? Here Jinhe company you explain one by one! Many classification of the boiler, the boiler can be divided according to use, can be divided according to the structure, the type of fuel boilers, but also you can press the water cycle in the form of pressure classification. It can be used as boiler thermal power boilers and heating boilers. Power boiler comprising a power station boilers, marine boilers and boiler locomotive, corresponding to power generation, marine, and locomotive power dynamic. Heating boiler comprising a steam boilers, hot water boilers, hot tube boiler, stove and the heating medium heating furnace, to give a corresponding steam, hot water. Hot air and the heating medium and the like. Boiler by the structure, divided into fire tube boiler and water tube boilers. Fire-tube boiler, including vertical and horizontal boiler boiler, water tube boilers and water tube boilers including horizontal, vertical, water tube boilers. By species classified as boiler fuel gas-fired boiler, oil-fired boiler and upgrade technical gas boiler and gas boiler, furnace oil and gas alternative --- pulverized coal boilers, gas boilers and other dual-use. Combustion gas boiler can be divided into layers by firing boiler, in fluidized bed boilers and combustion chambers. The latest fuel alcohol-based fuel boiler, he will greatly reduce the pollution of the atmosphere of a gas boiler. Evaporation of less than 20t / h is called a small boiler, evaporation to 75t / h is referred to as large boilers, evaporation of medium-boiler referred interposed therebetween.

How to do when severe water shortages steam qualified brown coal hot water szl boiler? In the event of a loss in water sometimes makes fireman process steam boiler operation, in the end how to solve it? How do we analyze today with severe water shortages steam boiler? In the operation of the steam boiler process, generally there will be some of the most common failure, the most serious is the boiler water shortages, lack of water is the main cause improper operation fireman, a long time to leave their posts, not the normal water supply. When there is a serious lack of water, do not have an immediate psychological pressure water supply, this is not correct, because the furnace severe water shortages, the various components of horizontal steam boiler is already red, not water supply, must wait until the boiler temperature drop immediately down, square and feed water may access the various components is malfunctioning. The above is how to do when severe water shortages steam boilers and today I will introduce? Content. After nearly a year of research and development company to launch coal, oil, gas steam boiler, the boiler is the biggest feature of this inspection is not required, all operations are automated, and now the case in Anhui, Jilin, Shanxi, Jiangsu and Guangdong have my company's .
