Condensing 1500kg Gas Fired Steam Boiler
4tph WNS gas-fired firetube boiler project for food industryBoilers are mainly used to provide steam for drying, refining, destaining and other processes in the productive progress of edible oil. As a children company of AnHui COFCO Biochemical, AnHui COFCO Edible Oil Co.,Ltd. is founded on 2000, producing premium quality edible oil from corn germ, rapeseed, peanut, soy bean etc.. In order to develop the circular economy, COFCO has taken an active part in energy saving and emission reduction these years. The company adopts reliable and advanced waste water treatment system, meanwhile, the environment protection facilities also produces ammonia sulfate, feed and methane as by products. Therefore, they’d like to use desulfuration methane as the fuel for boiler to improve economic returns. They have planned to order one set of methane-fired boiler. ZOZEN’s WNS series firetube boilers have drew their attention by remarkable performance. This kind of firetube boilers is adaptable for various fuels, including natural gas, methane and coke oven gas. Large corrugated furnace is adopted for complete combustion. Meanwhile, engineers of ZOZEN also add the condenser, economizer and other energy-saving equipment at the end of flue gas duct in accordance with actual demand of the company, which makes the thermal efficiency reach above 98%. Furthermore, it equips with advanced combustion apparatus for lower NOx emission.
Nongfu Spring has been committed to the production of natural and healthy drinking water, only after a simple filtration, without changing the water quality, maintain natural water features indicators, unswervingly follow the environmental, health, natural path of development. Fast boiler since its inception, focused on research and development of clean boiler design, adhere to the concept of environmental protection has become condensing gas boiler industry leader. The same faith, the same dedication to promote fast boiler and Nongfu Spring work together to create new environmental future.
Steam boilers What is the function? Too many in the form of condensing 1500kg fired steam boilers, would like to give a quick four tons of ordinary steam boiler talk. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Let me say a boiler pot. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, through the grate in the rear portion of the olecranon iron discharged from the machine to send out of the furnace slag. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessels, safety devices is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used. Boiler water must be softened, as well as water treatment equipment.
Gas 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 condensing 1500kg fired 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.
