Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.
What is the relationship between the boiler and the steam turbine and boiler WNS: boilers, boiler WNS What is? Boiler and turbine, What is the relationship? In addition, before the vote bottom steam heating boiler ignition, which has the specific role? These issues are important with regard to the product boiler and keywords, so the following immediately to give a specific answer, so, we also benefit from some of the harvest and inspiration, and to deepen familiarity and level of understanding of the boiler. 1. What is a WNS boiler? WNS boiler, the specific terms of the case, which refers to WNS 3500kg per hour vertical fired steam boiler, means automatic oil or gas steam boiler. And which uses all wet back horizontal and efficient combustion threaded pipe, and with good insulation design. Thus, in the thermal efficiency of the boiler, it is 85% or more. Moreover, this kind of boiler, also with a reasonable structure, process performance, etc., so, there is a good use effect. 2. Before boiler ignition vote bottom steam heating, which has a specific role? Before firing boiler, a steam-heated cast hearth words, in which the specific role, is as follows: a role: the metal can be uniformly heated, and the temperature difference h Amount love young drum wall thermal stress, thereby shortening the boiler Start Time. Role two: increase the temperature of the boiler furnace, which allows the boiler combustion stability after ignition. Three functions: to improve the boiler water temperature, and speed up the process of building the boiler water cycle. The role of four: to improve economic performance during startup boiler.

Principles of 3500kg per hour vertical fired steam boilers and solutions hydraulic external gear of Henan fast boiler's small series with you about the principles of steam boilers and solutions Steam Boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil three kinds of steam boilers, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, large steam boiler return of more than three horizontal structure . If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories. From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blowing into the combustion chamber is a lower place, such steam boilers greater resistance, require forced air. Steam boiler cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. Steam boiler flue gas from the back of the boiler, the steam drum of a boiler return line before the smoke tube, returned by two return rear smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. These are the works of steam boilers, steam boilers run course, ultimately, other devices, such as induced draft fan not only bear the task of exhaust fumes, or negative pressure necessary for operation of the steam boiler. As well as pressure vessels, thermometer, safety valves, pressure gauges, pumps, steam pumps, and so on. They are essential for steam boiler work. Pump leaks. Gear pumps for leaks during operation, leading to its actual output is smaller than the theoretical flow of traffic. The main channel is leaking gear pump: through the gap between both surfaces and both side surfaces of the gear cover side leakage, accounting for 75% to 85% of the total leakage of the pump; radial gear tip circle between the inner hole and the pump CLEARANCE ; gap by engagement of the gear leak. The gear pump due to the presence of a leak, so that the output pressure do not increase, the influence of the use of a gear pump. In order to solve the low gear pump output pressure problems, may be employed on both sides of the elastic gear plus floating collar or baffle manner, to reduce the leakage of the gear pump, the gear pump to increase the output pressure. Radial force imbalance. In the gear pump during operation, the pressure acting on the outer gears are not equal, resulting in the gear and bearing at the axle radial imbalance force. This unbalanced force will accelerate the radial bearing wear and reduce the service life of the bearings, the gear shaft deformation can also cause friction with the inner hole of the addendum pump, pump damage, so that the pump does not work. The solution generally adopted is: ④ opening pressure balancing grooves to the pump, the high pressure oil introduced into the low pressure zone, but will increase the pump leak, the influence of the volumetric efficiency of the pump; ② size reduction oil pressure chamber, acting on the teeth the pressure area is reduced, thereby reducing the radial force imbalance.
