Fang fast + Qiaqia, the power of innovation to bring the taste of happiness "Qiaqia, happy taste." Qiaqia food as essential goods along with leisure time, loved by the people, it can be said to be suitable for all ages. March 2, 2011 Qiaqia food (stock code 002557) listed on the Shenzhen Stock Exchange. Today, once a small workshop into a modern enterprise, committed to spread happiness Qiaqia food taste is king of roasted China, the products are not only popular in the country from the seeds to grow a little, but also exported to Asia, Europe and the United States more than 30 countries and regions, has become the world understand China snack food culture an important window.

Biomass fired customized 1 mw boiler fuel characteristics

Biomass fuel has the following main characteristics compared to coal:

1. Low sulfur content. Biomass fuels are mostly less than 0.2% sulphur, and there is no need to install a gas desulfurization device when burning, which reduces costs and is environmentally friendly.

2. Most of the carbon in the biomass fuel combines with hydrogen to form a low-molecular hydrocarbon. After a certain temperature, it thermally decomposes and folds out the volatiles. Therefore, biomass fuel is easily ignited,

3. The density is small. The density of biomass fuel is obviously lower than that of coal, and the texture is relatively loose, especially crop straw, which is bulky.

4. Less carbon. The highest carbon content in biomass fuels is only about 50%, which is equivalent to the carbon content of lignite with less generation.

5. Straw biomass contains a large amount of alkali metal elements (mainly potassium and sodium). In the combustion process of biomass, the main performance is that the adhesion of ash is strong, and slagging and clogging are likely to occur in the furnace. Ash accumulates on the heated surface of the tail.

Analysis and pressure steam customized 1 mw boiler burning issues of excessive treatment: this kind of boiler steam boiler, because it is an important site for the product, so in their knowledge and understanding of the, at least, should achieve a comprehensive and specific to this extent, so in order to further the product site, rather than just stay on the surface, and then, in the use of the product, there is a good use of effects. Therefore, in order to achieve the above objectives, the following will continue this topic, which reads as follows. 1. steam boiler, which is in use, whether the boiler must first obtain use permits, and then to use this kind of boiler? In addition, if classified according to their fuel, then, in particular, which has several? Steam boilers, because it belongs to special equipment, therefore, can not be directly used, relevant departments should first obtain use permits issued by the boiler, and then to use steam boilers. In addition, this kind of boiler, if classified according to the type of fuel, then, can be divided into three electric steam boiler, gas steam boiler and steam boiler fuel.

Coal-fired customized 1 mw boiler economizer economizer effect to save the name suggests is a secondary member of coal fired boilers and the like for the device, the principle is to use the coal-fired boiler economizer flue gas heat exchanger for heating the feedwater. Economizer heat absorbing smoke, reduced exhaust gas temperature, by improving the thermal efficiency of coal-fired boilers, to achieve the purpose of saving coal. Secondly, in the coal-fired boiler feedwater into the drum, since the exhaust gas after the preheating heater temperature increased, reducing the temperature difference between upper and lower walls of the drum, the drum reduces the thermal stress of the upper and lower walls coal-fired boilers, to reduce the vertical drum wall temperature difference due to damage, protect the safe operation of coal-fired boilers, coal-fired boilers to extend the life of the road.
