Fire Tube Structure and New Condition Gas Steam Boiler
The main structure of a natural gas boiler consists of a boiler shell, a tank, a switching chamber, a smoke pipe, etc. The boiler is suitable for various fuels such as light oil, heavy oil, natural gas, liquefied gas, and so on. The boiler has a reasonable structure and a double-layer reverse burning. It is beneficial to make full use of flue gas, and has the characteristics of small area, convenient installation and good steam quality. The working principle of natural gas boiler is: the water enters the boiler through the inlet, the water quality that meets the heating standard after the boiler is heated, the water is fed into the indoor radiator through the circulating pump, the heating is heated by radiation and convective heat transfer, and the water flowing through the radiator is flowing through the water of the radiator. Go back to the boiler and heat it up, and then go back to it. It flows into the radiator, so that it circulates over and over again. Moreover, the natural gas boiler system can also provide users with hot water to meet its basic needs, the temperature of the water quality in the boiler and the indoor temperature, after temperature sensor processing, the temperature signal is transmitted to the single-chip microcomputer. Through the corresponding driving circuit, to adjust the size of the corresponding pipe valve, and then by controlling the water quantity to control the water temperature, to achieve the purpose of heating, the user can also select the appropriate circulation pump according to the size of the heating range. This is also more economical and convenient.
The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase fire tube structure and new condition steam boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
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 fire tube structure and new condition 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.
The importance of water supply equipment Gas supply equipment continuous fire tube structure and new condition steam boiler steam boiler 1. The effect of gas boiler room in the boiler room of the water supply equipment is a very important device all the boiler system. It is responsible for steam boiler feed "raw material", it can be a need to use the normal production of steam. During the operation of the boiler, the water supply equipment necessary to support synchronous operation, in order to continue to supply feed water to the boiler, the boiler can get enough water supply in normal operation safely. 2. Classification feedwater steam boiler steam boiler water supply equipment, there are two methods of water supply, water supply and electric steam-driven water supply categories. Steam-driven water supply equipment mainly refers to water vapor and reciprocating pumps, spare typically acts on the boiler water supply equipment. Another method of comparison used is an electric water supply through an electric centrifugal pump for water supply and vortex. Steam boiler during operation usually needs water supply equipment with active control function, the choice of the water level drops to a certain position to take the initiative to open pump water to the boiler, the water to a certain position but also take the initiative to stop the pump "bit" type conditioning. Boiler feed water can also be (a) water conditioning or heating condition circulated. Therefore, the gas boiler are usually equipped with an electric centrifugal or vortex pump, not equipped with the movable steam supply equipment.
