Description
Technical field
The utility model relates to burning torch, particularly a kind of explosion-proof burning torch that is applicable to gas fired-boiler.
Background technology
In recent years, along with the raising of China's productivity, the develop rapidly of national economy, the raising of national life level all grows with each passing day to material and to various demands for energy.This needs more efficient, stable energy supply.Traditional electric power energy is a main fuel with oil products such as coals, has efficient, stable characteristics.
The coal that carbon is rich in burning is that the people is the No.1 arch-criminal of greenhouse gas emission.When traditional coal fuel produces electric power energy, also produced the energy that a large amount of carbon dioxide, sulfur dioxide etc. cause greenhouse effects." national economy and social development 11th Five-Year Plan outline " proposed energy consumption per unit reduction the Eleventh Five-Year Plan period about 20%, and total emissions of major pollutants reduces by 10% restrictive index.According to these two indexs, increase by one one-tenth as China's GDP is average annual, just need energy-conservation 600,000,000 tons of standard coals in 5 years, reduce discharging more than 620 ten thousand tons of sulfur dioxide, more than 570 ten thousand tons of CODs.This is the solemn commitments of Party and government to the people.For this reason, National Development and Reform Commission's " comprehensive programme of work of energy-saving and emission-reduction " of formulating together with relevant department is further clear and definite realizes the target and the general requirement of energy-saving and emission-reduction.
As a kind of cleaning, environmental protection, boiler oil efficiently, only produce a spot of water and carbon dioxide after the gaseous fuel completing combustion, reduced the characteristics that coal fuel produces a large amount of greenhouse gases from root.
China's each item is energy-conservation, reduce discharging the implementation of rules and policy, and the clean fuel gaseous fuel is being brought into play the irreplaceable important function of other energy as a kind of environmental protection, novel energy efficiently.
Air gun, burning torch are the important component parts of industry gas fired-boilers such as power station, petrochemical industry, for ignition of the boiler, combustion-supporting, steady combustion provide the energy support, are one of requisite key equipments of gas fired-boiler startup, stable operation.Present stage mainly comprises natural gas, methane, blast furnace gas, propane etc. as the gas of fuel.Because the good combustibility of gaseous fuel, the safe handling gaseous fuel is even more important.
According to the pertinent regulations of explosion-proof association of China and the explosion-proof rules of U.S. NFPA, the equipment with explosion-proof or explosion insulation performance must be used in the place of fuel gas.Burning torch is as the initial stage incendiary source of gaseous fuel, and its security performance can directly have influence on the operation of whole boiler, is related to the safety of people's lives and properties.
Gas fired-boiler must use explosion-proof burning torch.
Present stage does not still have the homemade gas burning torch that meets requirement of explosion proof fully in the industry, and most of explosion-proof burning torches still rely on import, and a lot of gas fired-boilers still use common fuel ignition rifle as the gas incendiary source.Because the shell of general point firelock is as an electrode of burning torch self, shell must be with the Boiler Metallic shell or is greatly well contacted to guarantee its electric conductivity.When the high-energy igniter energy outputs to burning torch, the burning torch shell, connect the lead place normal since the lead contact is bad, air pole is moist or extremely factor such as drying be created in the burner hearth external discharge.And common gaseous fuel such as natural gas, methane, blast furnace gas, propane etc. also can ignite under the electric spark of erg-ten.And the ignition energy of general point firelock is all greater than 12 joules, and the electric spark of consequent any energy all can be lighted the fuel gas in the environment.And will be explosion caused when the concentration of fuel gas reaches its explosion limit.This safe and stable operation, electric power energy to people life property safety, boiler normal, stablize supply and all constitute huge threat.
