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 3000 kg 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.
When the weather gets colder and colder, people will choose different ways of heating, one of which is more convenient is the fuel-fired boiler, but many people do not understand his use, so take a look at the following. Classified oil-fired boiler is a kind of boiler with many kinds of oil such as diesel oil, waste oil and so on. Its general structure and arrangement are similar to coal-fired boiler, and the common classification is mechanical type and steam materialized type. The characteristics of the bottom of the oil-fired boiler are to make the bottom of the furnace inclined to the back wall, which is the bottom of the heat preservation furnace, in order to obtain good combustion characteristics. This kind of boiler, for those who don't have a natural gas pipeline, Hope the boiler can run normally low cost, then the fuel-fired boiler is a very good choice. The fuel-fired boiler is an important symbol of the progress of the times, in order to serve the human being well and further perfect according to the needs of the people. Oil-fired boiler is designed in accordance with certain commercial standards, to a certain extent to ensure the excellent boiler, but also to a certain extent to improve the heat absorption strength of the boiler, then how should we use it? Design problems according to the oil-fired boiler inside the design of the boiler inner tank is larger, can store steam will be corresponding to more, suitable load capacity will become stronger, can be To meet the needs of different users, the cleaning of internal gall is also more convenient. The fuel-fired boiler with fire tube structure adopts the structure of triple-reflux fire tube, and the flame burns in the combustion chamber with high thermal efficiency, energy saving and consumption reduction, so it is economical and convenient to use. According to the unique design of the boiler, the use of the oil-fired boiler needs to find a set of operation steps suitable for the boiler and give full play to its function.
Shanxi Province to respond positively to treatment advice on remediation since 2014, new registrations of 10 steam tons / hour coal-fired boilers and environmental supervision of the central group feedback, recently, government inspectors focus group, conducted a comprehensive inspection of coal-fired boilers activities, to grasp the progress and corrective measures to ensure the successful completion of the renovation work.
The statistics, since 2014, Datong new registered 10 steam tons / hour and a total of 48 coal-fired boilers, according to the provincial Bureau of Quality Supervision requirements, the county district special equipment related regulatory authorities have the 48 legally registered boilers Log off, and conduct regular inspections. As of to date, 36 units have been removed, still with 11 units, the remaining aspects of the transformation of a substance being born.
Currently, 11 boilers are still in use, some have been re-ordered natural gas boiler, gas pipeline work underway access; some have been able to replace air heating equipment; also because of the administrative division adjustment, need to further define the charge of the task.
Follow-up inspection staff proposed remediation work boiler suggested that there was any objection to the main regulatory responsibility, clear as soon as possible; dismantled boiler, strengthen follow-up supervision; boilers still in use, depending on the circumstances be accountable to county-owned enterprises; the ongoing transformation of the boiler, a clear transformation is complete to confirm compliance and acceptance of responsibility department, and follow-up supervision.
