Natural Circulation Low Pressure 6 Ton gas Boiler
In the natural circulation low pressure 6 ton boiler market, oil and gas boilers, coal-fired boilers, and biomass boilers occupy almost the entire market. Among them, many countries and regions have demanded the use of clean boilers because of their emphasis on environmental protection, which has also promoted the development of environmentally friendly oil and gas boiler manufacturers.
Gas natural circulation low pressure 6 ton boiler heat loss through the combustion of fuel gas boiler, will release some heat, which will supply part of the user, some will be recycled and part is inadvertently wasted. So these are wasted heat lost through the ways in which it (1) heat losses:? Flue gas exhaust gas boiler part of the heat into the atmosphere, causing the boiler heat losses, it is each boiler term heat loss Dazhong biggest one. The main factors influencing the heat loss is higher exhaust gas temperature and the amount of smoke exhaust gas temperature, the greater the amount of smoke, the greater the heat loss. Low exhaust gas temperature depends mainly on the number and operating conditions of the heating surface; the amount depends on how much leakage exhaust case and the furnace excess air, flue. (2) heat loss incomplete combustion gas: a part of the unburned combustible gas is discharged with the flue gas to heat loss caused by heat in the flue gas. The main factors affecting the incomplete combustion gas heat loss is the excess air and furnace structure. Excess air coefficient is too small, uneven air is mixed with fuel, easy to generate carbon monoxide and other combustible gases; excess air coefficient is too large, the furnace temperature is lowered, the combustible gas is not easy ignition and combustion. Furnace volume is too small, combustible gases in the furnace too late to enter the combustion flue gases caused by incomplete combustion heat loss. (3) heat loss: the furnace heat loss, frameworks, pipes, door opening caused by heat dissipation to the surroundings. Size depends on the heat loss factors of the size of the surface area of the furnace gas steam boiler, heat insulating properties and thickness, the outside air temperature and the flow velocity. Electric heating reactor common external damage: an electrically heated reactor despite external corrosion has a high etching resistance against acid and alkali resistance, but our electrical heating by the heating apparatus is a kettle layer and an outer tire iron constituted. Such a medium is iron acids and bases are not corrosion-resistant. If we would have the production process if the reactor cover or screwed pipe joints without seal failure or leak acid tire iron reactor apparatus for electrically heating the outer corrosion. Corrosion support member 2. The reactor was heated electrically heated reactor during installation, support or other support member may be mounted directly on the floor, due to the long manufacturing operations on the floor may be deposited with corrosive media, so that for support our reactor electrically heated apparatus corrosion, resulting in the supporting force of each of the support produces a change resulting in a change in stress in the damage produced during heating layer. 3. The electrically heated reactor stress spout in the electrically heated reactor, when the steel of the pipe and the pipe joint, since the thermal deformation and the reaction was heated electrically heated autoclave vessel or duct stressed cold might damage the pipe.
6 tons adjusting a combustion gas steam natural circulation low pressure 6 ton boiler, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
As a leader in the fast side condensing gas natural circulation low pressure 6 ton boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
