Hot Selling Natural Gas boiler Commercial Turkey

Recently, Shaanxi Province, issued a "Boiler Air Pollutants Emission Standards" ( "Standards"), the "standard" in the concentration of air pollutants emission limits thermal power hot selling boiler commercial turkeys and industrial boilers, we have developed a monitoring requirements.

Thermal power generation boilers including boilers of various capacities and various gas turbine capacity, fuel main types of coal, natural gas, oil, biomass, like other gas. Use gangue, oil shale, petroleum coke, fuel, sludge and other coal-fired power boilers reference emission limits fired boilers performed.

Industrial boilers including industrial boilers, various types of fuel capacity mainly coal, gas, oil, biomass, and so on. Boilers using coal, coal water slurry, coal waste, semi-coke, petroleum coke, oil shale and other fuel fired boilers performed with reference to emission limits. Using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.) with reference to the boiler exhaust gas boiler limits performed. Oil and gas dual-fuel boiler in accordance with the type of execution are oil-fired boiler and gas boiler emission standards. Other types of fuel mixed fuel boilers by performing more stringent emission standards.

Industrial hot selling boiler commercial turkeys and control systems of foreign countries: (1) is designed to not only focus on boiler heating systems also pay attention to both attach importance to the development and integration of hardware, pay more attention to the boiler control model and control software research and development; (2) pay attention to the reliability of the control device , economy, such as small oil, gas boiler still use many relays, contactors logic control; (3) control the boiler operation is fully automated, requires less or no operator; (4) larger capacity boiler widespread installation of combustion optimization system based on an online industrial control computer; (5) the use of group control technology while controlling put into operation and out of multiple boiler according to the actual load; the use of (6) information technology continues to improve, medium and small boilers can be transmitted via the mobile Internet managers to operate the boiler boiler operating conditions, overload alarm and other critical information, and to accept operator performs the operation command, the boiler operating data may also be connected to the building automation system via a local area network, the Internet ( BA), the wisdom of the factory system to go; (7) Internet-based remote monitoring system boiler was Development and application. Compared with the boiler control technology and equipment abroad, mainly in the following gaps: ① slow combustion control technology, especially coal-fired boiler combustion control technology development; compared to the presence of on-line monitoring and sensor technology for combustion control developed ② large boiler the gap; the presence of reliability and developed sensor ③ boiler combustion control, actuators and control equipment compared to a big gap; ④ light weight hardware-oriented software for boiler control there is the negative impact of technological development; ⑤ remote operation and control, monitoring system still in its infancy, there is a large distance away from the application; ⑥ majority control equipment still in operation control based on boiler safety level, based on a handful of boiler control equipment taking into account the number of energy-saving, environmental protection and performance of the system control. 3 standardized "Twelfth Five-Year" period, the standardization of industrial boilers has made considerable progress to revise the "Boiler Safety Technology Supervision" of TSGG0001 and TSGG0002 formulate "energy-saving boiler technology Supervision" as the starting point, through the development of core boiler product standard GB / T16507-2013 "water-tube boilers", GB / T16508-2013 "shell boilers", on the basis of gradually straighten out the boiler standards with international standards and further amendments, including one after another on the GB / T10180 "industrial boilers thermal performance testing procedures "and other issues involving the boiler and related components, ancillary equipment design, manufacture, use and inspection of industry regulations and standards 62 (six of which industry technical regulations, national standards and industry standards 30 26, see Appendix H) and universal implementation, technical specifications and standards revised on the basis of implementing the security, the energy requirements of the market fully reflects the principles and spirit of the WTO, which greatly helps regulate and improve the overall technological level of industrial technology and competitiveness of the industry.

Combustion conditions provides rapid and substantially complete combustion of 1, a relatively high furnace temperature: the chemical reaction is the basic condition of combustion, fuel ignition and stable combustion, burn have a significant impact, maintaining a suitably high temperature furnace to important. Of course, when the furnace temperature is too high, consider the problem of slagging hot selling boiler commercial turkeys. 2, the air supply amount: the amount of air supply, is to provide enough oxygen for the fuel, which is the original conditions of the combustion reaction. Air supply, fuel not get enough oxygen, it can not achieve complete combustion. But excessive air, the furnace temperature will lead to loss and exhaust loss increases. 3, good mixing conditions: Mixing is an important physical conditions of the combustion reaction. Mixing the hot flue gas in the furnace is heated to reflux of the pulverized coal flow, so as to rapidly fire. Mixing in the furnace is strongly perturbed stream to provide oxygen to the soot combustion stage surface, outward diffusion of carbon dioxide, and to promote post-combustion of the fuel burn, it is an indispensable condition. 4, enough burn time: the fuel in the furnace for a time sufficient to achieve a high degree of fuel burn, which requires a large enough volume of the furnace. Proportional to the volume of the furnace and boiler capacity. Of course, the furnace volume is also characteristics of the fuel combustion, easy to burn fuel, furnace volume can be relatively small. For example, the same capacity of the boiler, furnace volume of fuel than pulverized coal furnace is small, and vanished without burning furnace volume than coal burning bituminous coal furnace volume slightly larger.

After gas-fired hot selling boiler commercial turkeys for low-nitrogen transformation impact: environmental protection efforts continue to increase, the provinces and cities have introduced various environmental policies. Air pollutant emissions is one of the main issues of governance and environmental protection sectors. For gas-fired boilers for low-nitrogen transformation has also become popular, such as Beijing, Tianjin, Zhengzhou, Xi'an and other places are carrying out renovation work and out of the boiler. Natural gas as a clean energy, can be reduced nearly 100% of the sulfur dioxide and dust emissions, 60% of carbon dioxide emissions and 50% of nitrogen oxide emissions, and help to reduce acid rain, global warming alleviate, reduce proportion of the amount of coal energy important energy; corresponding gas boiler has gradually been used and popular. But not as long as the use of gas-fired boiler can, according to China's introduction of the latest air pollutant emission standards, Beijing and Tianjin, the Yangtze River Delta and other regions, and Zhengzhou, Xi'an and other cities ever to perform the most stringent air pollutant emission standards --30 mg / cubic meter. Many enterprises due to gas-fired boiler installation time relatively early, current nitrogen oxide emissions higher than this standard, however, when the burner exhaust emissions can not meet the standards formulated by the state, need to deal with the transformation of low nitrogen may continue to be put into use .
