plc control gas fired steam boiler

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 plc control 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.

Central heating hot water boilers for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.

Steam boiler plc control fired steam boiler price Price: works steam boiler is heated in the drum and water is converted into steam, fire gives off heat in the furnace. Qiang boiler plumbing materials sales center is located in the southern suburbs of Datong City, is a design, sales, installation and service of integrated modern enterprise management. The main environmental operating boiler, a steam boiler fired boiler, a heating furnace, steel radiators, cast iron radiators, canned motor pump, the pump piping, air-conditioning water, galvanized pipe, PP board tanks. Details can be found! Works (in Pulverized example) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (excluding the DC furnace), into the separated saturated steam superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 1, the working principle (as an example in pulverized coal fired boilers) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (except for the DC furnace ), the separated saturated steam enters the superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 2. Pulverized coal boiler operation, the position of the center of the flame will affect evaporation. Generally, low center of the flame will lead to greater evaporation, and the high center of the flame will lead to slow evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Typically, superheated steam, in particular the reheat steam temperature in the lower center of the flame, and vice versa. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined.
