First, the economic advantages and a gas boiler, because gas in the ash, low sulfur and nitrogen than coal combustion, very small amount of dust in the flue gas, the gas discharge apparatus is easy to meet the state required standard, can greatly reduce the pollution of the environment, good environmental performance. 2, the absence of gas boiler heating surface contamination, slagging, wear problems, so you can use a high-speed cigarette, to reduce the size of the convection heating surface. Such fumes away less heat energy, thermal efficiency of the boiler is also higher. 3, the attachment device does not require gas boiler gas, slag, dust removal machine, grate like, saving the boiler equipment investment. 4, due to the use of natural gas piped gas boilers for fuel, gas boilers do not need fuel storage, saving transportation costs, storage space and labor management, and many other costs, so the cost of this off than coal-fired boiler more affordable. 5, the boiler operation, regulation and reduce heating costs. 5.1 gas heating boiler load adaptability, in accordance with the load (water temperature) flexibility to adjust the size of the fire. 5.2 System start fast, reduce the consumption of all kinds of preparatory work brings. 5.3 Due to the small less ancillary equipment, power consumption is lower than coal-fired boilers. 5.4 less gas inside the magazine, high and low temperature boiler heating surface corrosion does not occur, boiler continuous long run, less failure. 5.5 accurate gas metering simple, easy to adjust the amount of gas supply. 6, in reducing equipment maintenance, gas burning boilers coefficient simple equipment, thus requiring less maintenance equipment maintenance, long life heated tube. 7, gas-fired boiler simple to operate, easy to achieve automatic control. Second, the environmental benefits of gas boilers: gas boilers due to the combustion of fuel in the combustion process, and clean burning, non-polluting emissions, is by far the most environmentally friendly energy sources. Coal combustion emissions containing sulfur and ash content are more environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise. Third, differences in coal-fired boilers and gas boilers: because of different physical and chemical properties of coal and natural gas, and therefore, there is a big difference in characteristics of coal-fired boilers and gas boilers. 1, combustion: fuel fired boiler combustion layer, fired by coal chain grate conveyor plane, the complete combustion process in the furnace. While the combustion gas boiler combustion chamber, the gas is mixed with air in advance is set in proportion to the burner, injected into the furnace through a nozzle, the torch was installed in the furnace to complete combustion. 2, combustion products: coal is mainly composed of C, H, S, O, N, and other elements composed of ash and water, but not the mechanical mixing of these components, but a very complex compound. After the coal combustion heat release and smoke into the hot air generated by the SO²SO³NOx, pollution of the environment and the human body can cause damage. And the main component of natural gas is methane (CH4) gas, and a small amount of non-hydrocarbon gas, generally free of moisture and ash after the combustion of natural gas, mainly CO2 and water to generate and emit a lot of heat, deleterious SO2, SO3, NOX coal and other emissions is relatively much less. 3, automatic control of the boiler: coal-fired boiler due to factors coal, coal seam thickness, the amount of blowing, the wind amount, and the air volume distribution grate speed limit, to be difficult to automatically adjust the operating parameters of the boiler according to the load. Less impact on the factors of the gas boiler, the burner can be adjusted only according to the size of the fire load, easy to achieve automatic control.
Small oil-fired boiler flameout protection device use: small oil-fired boiler furnace space Product Introduction small oil-fired boiler of large and adaptable load capacity. Rational design of steam separator apparatus built to meet user requirements need to use higher quality steam. Furnace open manhole, head holes, hand holes, to facilitate the internal furnace to clean up, make repairs, maintenance is very convenient. Boiler safety interlock with multi-level protection: protection pressure switch (higher than the set auto stop and pressure), the low water level protection (boiler water level is below the warning level in the body, and automatically cut off power alarm), the protection valve (boiler pressure exceeds the pressure of work, discouraged automatic blood pressure), ensure that the boiler in a variety of conditions foolproof, secure home. Mechatronics combined organic appearance, new sophisticated, compact, less space, easy to transport and install. Thermal insulation materials and the use of new high-quality white color plate package, lighter in weight, good insulation properties, beautiful, not rust. Use flameout protection device for small oil-fired boiler to prevent furnace explosion, the fuel (gas) boiler must be set flameout protection means functions combustion in the monitoring of the furnace (including an ignition when the ignition failure or combustion halfway off, typically 5 seconds the re-ignition, run 1 second, off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds after purging, and various auxiliary blowers automatically cut off power, the boiler stop running.) by the flame monitoring and control device component. Role is to monitor the flame control device signals the presence of a flame or interrupted. The main use of the photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an infrared type or ultraviolet type, A photoelectric conversion element, the working principle of the light converted to the corresponding strength of the radiation intensity of current. And a linear output state, sometimes weak induction current, through amplification, in order to have an effect on the controller.
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.
