condensing gas fired boiler manufacturers
Established in year 1945, ZG is a manufacturer and international trader specialized in the research, development and production of Power Plant condensing fired boiler manufacturers and Spare Part; Gas fired boiler; biomass fired boiler . We have rich experience to help power plant owner to solve all kinds of power plant boiler problem.
As fast condensing fired boiler manufacturers manufacturer specialized in the production of gas boilers and electric boilers, it has gone through 20 years of development history. The energy-producing gas boiler and then fully welded to the pre-expansion, and finally Expansion technology, both to prevent corrosion of the tube gap, but also enhance the welding strength; threaded pipe using a high heat transfer coefficient, heat strengthening effect on the spread , reduce exhaust gas temperature and improve the thermal efficiency of the boiler. With industry-leading gas boiler products and perfect after-sales service, fast boiler boiler by many users of gas acceptance and trust.
China Dunhuang International Hotel relevant responsible person said, party fast or aftermarket both in pre-sales, remained consistent patient service, we have solved many difficult problems, with fast condensing fired boiler manufacturers, we are assured. --customer feedback
Gas condensing fired boiler manufacturers 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.
