5 tons wns condensing gas fired steam boiler

Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.

Fuel gas control step and the blowing process air volume of the total fuel gas 5 tons wns condensing fired steam boiler steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.

Successful ignition of fuel 5 tons wns condensing fired steam boiler can not run, because of those common oil gas powered steam boiler applications, all of you should ignite the fuel steam boiler in the application process, no way ignition is also the most common problems. Fuel steam boiler in the application process, most likely resulting in no way ignition, resulting in fuel steam boiler can not run normally, small series to introduce you to a steam boiler does not ignite the fuel to run those common reason. Fuel steam boiler can not run common ignition of those reasons: First, the ignition problems: pulse ignition and control systems such as the one of which has caused the problem, the fuel steam boiler can not start. Second, the battery thing: to be very important to see if the battery is a battery in the end is not too aging. The charge is not standard, the same can not let steam boiler fuel ignition. Third, the water pressure thing: at the inlet steam boiler fuel filters block the formation of water can not flow normally through the clean up clean ok. Fourth, the pulse valve problems: If the boiler ignited fuel vapors to ignite division saw sound, no pulse valve "despair" squeak, probably for the pulse valve is damaged or degraded, pulse valve degeneration, will not manipulate, the beginning of the ignition operation when closing a flow will hit a fire, but the fire immediately and confinement; pulse valve before confirm whether there is a problem to confirm whether normal ignition actuating member, if the fault can not pull the valve actuating pulse. V. ignite feelings needles or needle thing: fuel steam boiler ignited hand shift. You can change or correct the ignition pin arrangement; if feelings of degradation promise things, as long as the feeling wiped clean arranged on it. Six, usually no way to exhaust smoke tube. Smoke tube steam boiler with a fuel block, clean breathing tube blockers smoke tube is too long, the configuration is not correct. Referring may be configured to inform two coaxial cigarette heater tube. VII vapor setter joint problems: fuel steam boilers, water vapor degradation intimal flap valve or joint damage, not the weak control push button switch; weak bad control switch button.

Beiqi Panther car 6 tons of steam condensing one fuel gas 5 tons wns condensing fired steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
