High pressure 5 ton gas fired boiler for industry
The oil and gas high pressure 5 ton fired boiler for industrys produced by ZG boiler pay great attention to high efficiency, low nitrogen and environmental protection. Oil and gas boilers are often used for natural gas. Natural gas contains almost no fixed nitrogen, so the fuel type is negligible. The factors that generally affect the formation of thermal oxides are flame temperature, excess air, mixing time of fuel and air, and the like. The fuel gas boiler produced by ZG boiler is an ideal low-nitrogen environmental protection boiler.
New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the high pressure 5 ton fired boiler for industry. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.
Gas high pressure 5 ton fired boiler for industry 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.
