A burner is a device used to eject a mixture of fuel and air in a certain way.Burners are classified into industrial burners, burners, civil burners and special burners according to their types and application fields.
To average consumer, to burner seems to have some strange, but in fact in generalized burner concept, domestic water heater, gas range, and lighter can be considered as a burner.In daily life, the application of industrial burner is very common and closely related to our life.Industrial burners commonly known as burners, there are many types of specifications, fuel oil, gas (gas), coal (pulverized coal/coal water slurry) several categories.It has a wide range of applications and is used in industrial applications where fuel is required to be burned to heat materials or reactions.
Domestic burners lack innovation Riyadh burners leading the international market
Burners have a wide range of target groups, including boilers, smelting furnaces, furnaces, heat treatment and other fields, and heat energy related industries, combustion system is essential.Compared with Europe and other developed regions, China's burner technology has a relatively short history of development.Copy & throughout;To make money, simply put, there is no innovation, which is why most domestic manufacturers cannot compete against imported burners.
At present, there are many famous brands of burners in the world, such as American McKesson, German wessel, Italian Riyadh, and black & white, among which, Italian Riyadh burners are the most famous. In the world industry, its sales volume and market share rank the first in the world industry.Riello co., LTD., founded in 1922, on the Italian mainland by a manual mill, as well as numerous collectivization enterprise, the original single engaged in production and sales of fuel oil burner to include seven brands, more than 50 patents technology of boiler, air conditioning and burner three major series of products, from product development and production to sales and service.
Imported burners to compete with dashuhe thermal engineering service to win the market
Italy Riyadh co., ltd. entered the Chinese market in the early 1990s, and set up a Beijing office in 1996, to a strict regional agent system, improve the parts supply system to carry out sales in China.Over the past ten years, under the joint efforts of many agents above the provincial level, Riyadh burners in China's burners market from behind, ranked first.Beijing xuhe global engineering equipment co., LTD. (xuhe thermal engineering) is one of the biggest agents of Riyadh burner.
Surehot.com is a leading supplier (wholesaler) of burners and components in China.The company is adjacent to Beijing zhongguancun shangde high-tech park, surrounded by dozens of large and medium-sized logistics companies, more than a number of express companies to provide door-to-door service, logistics network to the whole country.
Xuhe thermal engineering customers include large oil, industrial and mining enterprises, hotels, hospitals, residential areas, burner maintenance and maintenance enterprises, as well as individuals proficient in burner.Xuhe thermal engineering has long been focused on burner and accessories wholesale and sales, burner installation, burner maintenance.Most of the company members have professional knowledge of burner and accessories, is one of the most professional burner sales, installation team in China.Based on these advantages, in the fierce market competition, xuhe thermal engineering has won the broad market with its excellent service and won the extensive customer support in the burner market.
At present, there are thousands of companies using xu grain thermal (wholesale), sales service in Beijing, Shanghai, guangzhou, shenzhen, hangzhou, tianjin, chengdu, chongqing, such as large and medium-sized cities, and shandong, shanxi, henan, hebei, hunan, hubei, guangdong, guangxi, heilongjiang, liaoning, zhejiang, anhui, jiangsu, fujian, yunnan, guizhou, jiangxi, surprisingly, jilin, qinghai, shaanxi, ningxia, qinghai, xinjiang, gansu, Inner Mongolia, such as dozens of provinces.
At present, the traditional fossil fuels such as coal, oil and natural gas have brought many problems such as environmental pollution and greenhouse effect to human beings.
There are many petrochemical and chlorine-alkali enterprises in China. Many petrochemical and methanol hydrogen production enterprises will produce a large amount of industrial tail gas with hydrogen content of 50%~60% or even more than 90%, which is called hydrogen-rich tail gas.
Hydrogen - rich tail gas is flammable, explosive, large, difficult to transport, and contains certain harmful organic matter, direct emission of environmental pollution;Treatment and utilization of hydrogen-rich tail gas is not only conducive to environmental protection, but also can save energy and reduce costs, thus improving the economic benefits of enterprises.
The "medium pressure air-tumber" atomized burner developed for burning straw oil has good applicability not only to straw oil, but also to bio-oil and petroleum oil.This kind of burners can be used to realize the normal combustion of heavy asphaltene and colloid and inferior oil with high density.
Fuel more intelligent control system, adopt international famous brand PLC as the core controller, according to different fuels, the choice of different control procedures, to realize the automatic ignition, automatic flame-out protection system, automatic adjustment, automatic wind load and coal proportion adjustment of oil and gas, combustion fault automatic monitoring alarm, can implement chain and equipment protection, at the same time, the control system can also be used with equipment integration for an organic whole, to realize automatic equipment operation parameters setting and burner operation parameters matching, improve overall equipment automatic control effect.
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.
New energy enterprises are not only the direct beneficiaries of clean energy consumption, but also important participants, bearing important responsibilities.Participate in the spot power market and auxiliary service market, improve the system dispatching ability in a market-oriented way, and promote the consumption of clean energy.
