coal fired steam boiler 30

Do you know what it is gas energy saving boiler gas boiler energy-saving and environmental protection Many customers do not believe, how coal energy-saving environmental protection? Zheng Boiler Group today for everyone to analyze environmental history of the gas boiler. Energy saving gas boiler pot Zheng Group production of a new product, a gas coal fired steam boiler 30. Energy saving gas boiler pot Zheng Group production of a new product, a gas steam boiler and gas hot water boiler, gas steam boiler models which are mainly DZL steam boiler gas chain, DHL chain gas steam boiler, SHL chain gas steam boiler SZL chain and energy-saving gas steam boiler and circulating fluidized bed boilers. Zheng pot boiler gas saving and environmental protection are "perfect green and environmentally friendly boiler boiler auxiliary boiler machine environmentally friendly application process installation service" model pioneered go on the road "environmental effects Enhancements". In addition to these types of environmental protection boiler, auxiliary equipment, environmental protection is also an important part of the environmental process. Energy saving boiler fuel gas separation efficiency as high as 97.97%, combustible low-quality coal, good desulfurization effect, can significantly reduce sulfur corrosion of equipment, in favor of low quality coal combustion, coal adaptability strong. Boiler fan low energy consumption, high economic efficiency, and can effectively avoid the fan big horse car phenomenon. To more than dust and coal in the coal auxiliary, not only an automatic cleaner, convenient safe, maintenance.

The heat loss of exhaust smoke is the largest of all kinds of heat loss in boiler. Generally, the heat loss of exhaust smoke is 6% of the heat fed into the furnace, and the heat loss of exhaust gas increases 0.5% when the temperature of exhaust gas increases by 12 ℃ and 15 ℃. So the exhaust temperature is one of the most important indicators of boiler operation. The following are several possible causes of increased flue gas temperature in the furnace: (1) slagging and ash accumulation on the heated surface. No matter it is the slag accumulation in the water-cooled wall of the furnace, or the ash deposition in the superheater, convection tube bundle, economizer and preheater, the thermal resistance of the flue gas measurement will increase, the cooling effect of the flue gas will become worse due to the deterioration of the heat transfer, and the exhaust temperature will rise. (2) excess air coefficient Big. Under normal conditions, the exhaust temperature increases with the increase of excess air coefficient at furnace outlet. After the increase of excess air coefficient, although the amount of smoke increased, the rate of smoke increased, and the convection heat increased, the increase of heat transfer was not as much as that of the increase of flue gas. It can be understood that after the increase of smoke speed, the flue gas leaves the heating surface without time to transfer heat to the working fluid. (3) the air leakage coefficient is too large. The flue gas leakage in the furnace and rear shaft of a negative pressure boiler is inevitable and the leakage coefficient allowed by a certain heating surface is specified. When the air leakage coefficient increases, the effect on the exhaust temperature is similar to that of the superheated air coefficient. And the air leaks away. The closer the furnace is, the greater the influence on the rise in exhaust temperature. (4) Water supply temperature. When the steam turbine load is too low or the high pressure heater is out of line, the feed water temperature of the boiler will be lowered. Generally speaking, if the fuel quantity is kept constant, the heat transfer temperature difference of the economizer decreases and the heat absorption of the economizer decreases when the feed water temperature is increased, which makes the exhaust temperature increase. (5) moisture in the fuel. The increase of moisture in the fuel increases the amount of smoke, thus increasing the exhaust temperature. (6) Boiler load. Although the boiler load increases proportionally, the amount of smoke, the amount of steam, the amount of water supplied, and the volume of air increase proportionally, however, the flue gas temperature at the furnace outlet increases proportionally. Increase, so that the exhaust temperature increased. After increasing the load, the outlet temperature of the furnace increases, the heat transfer temperature difference of the convection heating surface increases and the heat absorption increases. Therefore, the more the convection heating surface is, the less the influence of the boiler load on the exhaust gas temperature is. (7) fuel varieties. When the low calorific value gas is fired, the radiative heat transfer in the furnace decreases due to the decrease of furnace temperature, and the non-combustible components in low calorific value gas, mainly N _ 2, CO _ 2 and H _ 2O, increase the amount of flue gas, so the exhaust temperature increases. Although the excess air coefficient of furnace outlet is lower than that of coal burning, the ash content in the fuel oil is very low after the pulverized coal furnace is changed to burn oil, although the excess air coefficient at the furnace outlet is lower when burning oil. There is no larger ash particle in flue gas, and there is no cleaning effect of larger ash particle on the heating surface, and the convection heating surface is polluted more seriously. Therefore, combustion is not good, often smoke-emitting boiler smoke temperature rise. When there is a steel ball dust removal device at the tail, the exhaust temperature is slightly lower than that of burning coal because the tail is cleaner. (8) the operation mode of pulverizing system. For a closed pulverizing system with a silo, when the pulverizing system is in operation, as a part of the water in the fuel enters the furnace, the furnace temperature decreases and the flue gas increases, and the cold air leaking into the pulverizing system enters the furnace as a primary air during the operation of the pulverizing system. Reduction of air flow through air preheater To raise the exhaust temperature. On the contrary, when the pulverizing system is shut down, the exhaust temperature decreases.

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.
