What is its auxiliary boiler feedwater oxygen has several categories? Boiler, I believe we are not unfamiliar with and understand it, if you have been concerned about the site and read the relevant article and master the relevant knowledge and content words, so below, it may be in front of the existing foundation, to continue the products of study and work, so that we can make progress in their learning and development road, and at the same time, you can also reach the intended target as quickly as possible. 1. ship boilers and boiler land, they are the same? Can GM? Marine boiler, which is used to generate steam, or fuel for heating domestic water, and may also be in the kitchen in the ship. However, it is compared with a land boiler, there is a big difference, such as shape and size. So, they are not identical, nor is it universal. 2. auxiliary boilers, there are a few main categories? Auxiliary boilers, which can be divided into six categories, the specific terms, it is the coal slag or counseling classes, containers, water treatment class, class fans, smoke and dust classes and appliances category. Wherein an expansion device containers, and other such sub-cylinder, the fan type blower and is mainly induced draft fan. The appliances, mainly for electric and control these two aspects.

Henan combustion control and adjust fast boiler boiler company to introduce small series with the boiler combustion control and adjustment. 1 coal fried steam boiler combustion process is the basis of all the work process of the boiler, from the safe operation of the economy, environmental protection point of view, how to properly regulate the burning furnace, saving coal consumption is the responsibility of each fireman. 2 hot water boiler combustion conditions primarily by uniformly supplying the fuel, and air distribution adjusting reasonable combustion equipment is achieved, the coordination of the three, to ensure stable combustion conditions, economy, safety. When coal and boiler load changes, will need to adjust the amount of coal feed and the amount of the wind, in order to obtain a normal combustion conditions. Indicator 3.1 normal combustion conditions 4.8.3 normal combustion means: timely fire burning strong, ash burnout. Specific requirements:. A fuel inlet from the anterior arch 0.1-0.15 m fire, gray ash ex chain at the 0.3-0.4 m burnout. B. fire bed smooth, dense and uniform flame, without flame or blown partial blackening phenomenon. C. Flame intermediate white light, two dark, the fire grate bed length representing more than 3/4 of the effective length. D. pale gray smoke or nearly colorless. In order to achieve good combustion conditions, must maintain a high furnace temperature, the temperature of the upper layer is generally burner combustion layer preferably 1100-1300 deg.] C, may be determined according to the color of the flame. Furnace temperature and flame color relationship in the following table. The outlet temperature of the furnace can also be used to determine, 29MW boiler design furnace outlet temperature of 1017 ℃, 58MW of 998 ℃. 3.3 In the case of normal combustion, the oxygen content in the flue gas is constant, the oximeter, fireman can understand the situation of excess air in the furnace, the furnace excess air is generally mechanical 1.2-1.4%, of excess air and oxygen table below. Ash 3.4 combustibles content is an important sign of good and bad conditions of the boiler combustion, which fuel, combustion equipment, and operations are closely linked, general mechanical furnace ash carbon content should be less than 10%. 3.5 water boiler operation should ensure that in the case of no condensation of the tail to minimize exhaust gas temperature, exhaust gas temperature is controlled at 110-160 ℃. Adjusting and controlling the amount of coal to a fireman who adapt to changes in load, the supply must be based on different types of coal and the various stages of the heating season, the weather trend, the thickness of the seam is determined, the general control of the thickness of 80-100mm low load, medium load control in 100-120mm, high load control in 120-160mm. 2 fireman in specifying a seam thickness, to be due to the furnace, because coal should comprehensive analysis, on balance, for the ash content, water large, large particles, high ash melting point of the coal, generally the appropriate tone thick seam, opposite seam is to tune thin. Small particles of coal or pulverized coal and a low ash melting point of the plurality coal i.e. strong bonding to a thin coal seam. Generally the 3 or the boiler when the load change is not too large, the method should not be used to adjust the thickness of the seam. Because coal seam thickness adjustment can not be effective immediately adjust the load only when a large load changes, and long-term stable operation of the boiler in the new load considering regulating coal seam thickness. 4 seam thickness can be achieved by adjusting the height of the coal and layered coal hopper shutter speed of the drum. Shutter elevation coal, coal may be added into the same hierarchical improved coal hopper drum speed may be increased into the amount of coal seam in order to obtain a proper height, the height of the shutter must coal, coal hopper drum speed stratified and chain speed adjustment of the three. Given the limited level editor, inevitable errors and inadequacies, please correct me!

What are the methods to reduce pollution mill 1, check for leakage protection and maintenance of: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, repeated use of steam condensate: Textile mills require large amounts of saturated water vapor in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, the piping, valves and heat insulated flange experience pipes, valves and flanges waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery from the boiler chimney at a temperature of 360 ℃ smoking, sometimes discharged directly into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of textile machines Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.
