Difference between supercritical pressure biomass Burner and subcritical pressure light oil EBICO

　　In today's society has entered the era of knowledge explosion, the fierce market competition make us daily, is full of suffering consciousness, deep well and the future, nip in the bud, the competitive landscape of research and its development trend, only relying on scientific and technological innovation, to provide more professional, more close to the needs of customers products and services, integration of all kinds of resources at the same time, follow the international trend, constantly enrich the latest knowledge, combined with the actual need, enhance the level of professional talents and can make the enterprise develop in the competition.EBICO always takes innovation as the foundation of enterprise survival, insists on scientific research innovation, production innovation, process innovation and product innovation, and constantly improves and extends the product chain to meet customer needs.

　　The frequent occurrence of major climate disasters in the world in 2012 is the result of mankind's increasingly profound understanding of the destructive effects of climate warming.Climate warming is caused by the uncontrolled use of fossil fuels by human beings, which increases the carbon dioxide content in the atmosphere year by year, strengthens the greenhouse effect and destroys the laws of atmospheric circulation.Now the world is exploring new energy sources to replace fossil energy and scientific ways of industrial production and application. Solar energy, wind energy and nuclear energy have been developed and utilized practically.However, the development and utilization technology of biomass industrial energy is just beginning and will last a long time.

　　Biomass energy comes from solar energy and CO2in the atmosphere. Plants absorb CO2and sunlight in the atmosphere during their growth and synthesize various organic substances, some of which are used by animals to form animal energy.When the organisms and their products are burned, they release energy and at the same time release the absorbed CO2into the atmosphere in equal amount.For the global atmosphere system, the CO2increment of this energy use to the atmosphere is zero, which is called carbon zero emission.There is a huge amount of biomass fuel on earth. If fully utilized, it will play an important role in reducing CO2emissions.The development, research and utilization of solid, liquid and gaseous fuels of plant straw are under development.

　　Many projects to increase the flue gas external circulation, according to the on-site reaction, the flue gas recirculated condensed water is a lot, in winter, the wind duct will even freeze.This is because the hot and humid smoke and combustion fresh air mixed, mixed steam beyond the mixed air temperature of the saturated humidity, the excess steam formed condensed water.CO2 in the flue gas will dissolve in the condensed water. If the acidic condensed water enters the burner or fan, it will easily corrode the components of the burner or fan.Measures must be taken to prevent condensation from entering the burner or fan.Add heat preservation for recirculating smoke pipe, reserve condensate water outlet, fresh air and preheat.

　　Condensate water discharge device shall be set at the lowest point of each section of the circulation flue. If there is a mixing bellows, condensate water discharge device shall be set on the mixing bellows. If necessary, condensate water discharge device may also be set on the fan.Condensate water discharge device recommended made of water seal type, the highest point of the water seal lower than the lowest point of the flue gas pipeline, for the convenience of condensate water discharge.

　　EBICO always adhere to the "professional quality more assured and integrity to make service more intimate" service tenet.If we can think of it, we will try our best to do it.EBICO always adhere to the customer-centric, to provide customers with first-class service, namely care about the pursuit of customers, desire, provide personalized services, constantly launched to meet customer satisfaction of new products to meet customer needs, so that they enjoy meticulous value-added services.How to stand out in the fierce market competition is the common goal of all EBICO people.EBICO not only emphasizes the innovation of science and technology, but also studies the quality.Build credit with quality, build brand with service.

　　From the perspective of heat transfer calculation, the measures to reduce the smoke exhaust temperature are analyzed from the following aspects: increasing the heat exchange surface, improving the heat exchange efficiency of the heating surface, improving the heat exchange temperature difference by using a lower temperature source, and reducing the influence of corrosion on the heat exchange efficiency.As gas boiler host first meet the low nitrogen flame furnace volume and size requirements, the second host of convection heating surface is a main export in order to reduce the smoke temperature, general control in 150 ~ 250 ° C, in order to avoid the smoke temperature increases along with the flue design difficulty of heat preservation, high smoking temperature is too low will cause corrosion in furnace convection heating surface forming wall condensation, therefore, furnace domestic demand to design proper heating surface, the physical dimension more representative chamber size.Increasing the heat exchange surface should mainly consider increasing the heat exchange area of the equipment in the rear of the boiler, which is more favorable for rapidly reducing the exhaust temperature.The second is to have a lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, corrosion resistant materials can be used to improve its service life.The new structure of efficient heat exchange mainly adopts the form of staggered tube arrangement, efficient heat exchange finned tube, plate heat exchanger, etc., to increase the flue gas disturbance and contact surface, reduce the heat resistance of flue gas stratification, and improve the heat exchange efficiency of medium and flue gas.

　　The development of hydrogen-rich tail gas burner is to reuse the hydrogen-rich tail gas discharged from air for a long time, thus improving the utilization rate of hydrogen-rich tail gas and saving production cost.At the same time, hydrogen-rich tail gas burner plays a positive role in promoting energy conservation and emission reduction, and will play a positive role in promoting the environmental protection and the technological progress, development and expansion of the burner industry, producing good social benefits.
