fired tube gas boiler manufacturers

Problems coal fired tube boiler manufacturers gas boiler gas coal problems are: 1, more coal ash, 2, unevenness of coal particles, 3, coal contains a large amount of impurities, 4, a lower heating value of coal, 5 when combustion is not easy to ignite fire, 6, coal moisture content uncertain. 7, does not burn coal, slag high carbon content. In general, use is preferably designed coal boiler design coal or coal close, in order to ensure stable combustion. In recent years due to the growing tension surrounding the coal supply, coal supply has become diversified, coal quality is very different than before coal, have a great impact on the stability of the boiler combustion and normal heating operation. Impact of coal combustion boiler stable for: calorific value of coal is coal reflects an important indicator of good or bad, when the low calorific value of coal to a certain value, will not only affect the incomplete combustion instability and can lead boiler flameout, the outlet temperature of the boiler is difficult to compliance, affecting the normal operation. Volatile combustion and can be deposited at lower temperatures, as the combustion heat, the temperature rapidly increased coke particles, provide an extremely favorable conditions for ignition and combustion, volatiles further increased coke deposition and internal voids and the external reaction area, will help improve the speed of burning coke. Thus, the greater the content of volatile, nonflammable, the less fixed carbon in the coal component, the easier coal burning ember, devolatilization of many voids, increases the surface area of ​​the reaction, the combustion reaction is accelerated. When the volatile content is reduced, pulverized coal ignition temperature significantly increased, the hot increases, difficult fire, ignition time required becomes longer, the combustion stability is reduced, shifting the center of the flame, furnace absorbed radiation heating surface reduce heat, increase the heat absorption of the convection heating surface, the rear exhaust temperature, exhaust loss increases.

Different meaning of the data and the oxygen content of the exhaust gas fired fired tube boiler manufacturers: A boiler oil-fired boiler which, it is explained below target, because through knowledge and understanding of this kind of boiler, can broaden everyone's knowledge, and at the same time, familiar with the different boiler type, so as to achieve a comprehensive understanding of the boiler, do not miss any of which. 1. fuel boiler, 0.5 tons and 0.35mw, its meaning is the same as you? An oil boiler, and 0.5 tons 0.35mw these two parameters, which specifically refers to, and is not the same, because the former is the rated evaporation of the boiler, while the latter refers to the rated power of the boiler or the rated for heat. In addition, in the unit, the two are not the same. So, obviously, on this issue, that the answer is not the same. 2. Industrial boilers, oil-fired boiler is why the general level? In addition, the oxygen content in the exhaust gas boiler fuel, how much is more appropriate? Industrial boilers, if its use is oil-fired boiler, then, it generally is a Class B boiler, that is, the pressure of the boiler is rated at 2.5MPa or less. Oil-fired boiler exhaust gas oxygen content and, in general, is controlled within the range of 3% to 5% is appropriate. If less than 3%, the problem of incomplete combustion occurs.

New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the fired tube boiler manufacturers. After the furnace arch after the transformation, the people stove fuel from coal gate 0 Β· 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, fired tube boiler manufacturers flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
