6300 kw light oil steam boiler
After the gas-steam circulation pump approach failed for some time to use gas steam oven, it will produce a precipitate. At this point, we need to clean heat transfer oil furnace, but before cleaning, we need to know what kind of sediment, and then cleaned the right way, if the heat transfer oil, grease appears very easy to make the wall thermal resistance increases, will increase the production of energy, gas steam liquidity will deteriorate, production will be reduced, the operating cycle will shorten the life of the device will be. Shorten, which in turn affect production. Some of the more common gas 6300 kw steam boiler deposits are: sulfate, carbonate, silicon and iron. Acid sulfate does not bubbling, since relatively hard sulfates, carbonates decompose at high temperatures, the bicarbonate will dissolve, but the release of carbon dioxide will form an insoluble carbonate salt. When the temperature reaches 300 ~ 400 ℃, hot oil furnace thermally cracking occurs. It will produce carbon deposits on the inner wall and an inner wall, it affects the heat transfer efficiency. Easy to produce oil furnace heat transfer in high temperature environments. Thermal cracking, thermal polycondensation, and its kinematic viscosity increases, the fluidity deteriorates internal oxidation of the oil pipeline, oil conductive accelerated failure, the machine will be damaged, endanger human will be high. Steam oven gas processing cycle pump failure: (1) When the current is below the normal circulating pump, the circulating pump efficiency is lowered, the flow rate is reduced, the fouling of the heating pipe may be blocked, it should be cleaned. (2) circulating pump pressure constant, the current increases, flow decreases. Bad heat transfer fluid, the viscosity increased, should be replaced or regenerated. If the system does not remove water or aqueous decomposition newly heated conductive liquid should be immediately opened exhaust valve to the exhaust gas. (3) circulating pump current is reduced, the pump outlet pressure back to zero, indicating that the pump is not idle. It may be vaporized oil, gas and steam oven measures to find the cause vaporization; if the filter is clogged, the circulation pump should be evacuated and cleaned immediately opens the bypass filter; if the heating fluid contained in the new water or heated water, the system does not exclude the decomposition gas, the exhaust valves should be opened immediately exhausted.
To build greener homes, recently, the ecological environment of the Office of Hebei Province issued "on improving air quality guidance on the implementation of regional differentiation of access environment." "Opinions" clearly states: Shijiazhuang, Baoding and other eight cities as a red zone atmospheric transmission channel, a ban on new industrial projects and expansion of 10 large iron and steel, thermal power, cement and so on.
"Opinions" also pointed out that the province's administrative regions and the municipalities and districts male An District, Dingzhou City, Xinji City administrative area, is strictly prohibited new construction, expansion (except for cogeneration and the same amount of alternative projects) coal; a ban on new , expansion of production capacity of iron and steel, cement, plate glass, petrochemicals project (excluding off-site relocation of upgrading) and 35 tons of steam coal-fired boilers; prohibit new emissions intensity below the access conditions of other industrial projects.
Handan, Xingtai, Shijiazhuang, Baoding, Langfang, Tangshan, Dingzhou, classified as a red zone xinji atmospheric transmission channel. Within this administrative area (except city back removal capacity), to prohibit new and expanded (except equivalent replacement) steel, thermal power (except CHP), coke, cement, lime, gypsum, fertilizer, general casting of ferrous alloys, iron alloys smelting, carbon, other industrial projects using coal as a fuel; Jing Kun high-speed east, north wing black high speed, and Langfang, Baoding and Beijing bordering county area designated as coal ban areas, not in addition to the approval of central heating coal-fired project.
Future, Hebei Province, will strengthen self-examination, government oversight and something in the ex post regulation, the implementation of various construction projects of environmental protection requirements as well as changes in environmental quality, pollutant emissions such as the implementation of dynamic monitoring of the implementation of environmental access requirements for non-construction strictly punished according to the law project, supervise the rectification of the problem is serious, shut down or banned. Meanwhile, according to relevant laws and regulations, environmental protection requirements and regional environmental quality changes and other regional differentiation environmental access requirements will be adjusted in due course.
A boiler is an energy conversion device that outputs steam, high temperature water or an organic heat carrier with a certain amount of thermal energy. The boiler can be used for heating, hot water supplying, industrial steam supply, power generation, etc. Therefore, the application of boilers is very common. From the fuel, boilers can be divided into many types. The oil and gas boiler is a kind of boiler that uses natural gas, gas, oil, light oil, heavy oil, etc. The boiler uses gaseous fuel or liquid fuel, and the fuel can be delivered in the form of a pipe, which is convenient to use. With the strengthening of environmental protection and energy conservation awareness, many boiler manufacturing companies have also made achievements in these areas. Such as ZG boiler low nitrogen condensing oil and gas boiler to achieve ultra-low nitrogen emissions, and the boiler's thermal efficiency is high.
Steam Gas Gas Desulfurization to achieve excellent results steam oven gas steam oven must sample tests, the thermal conductivity was measured quality of appearance, flash point, viscosity, acid, water, and carbon residue, provided with heat transfer fluids plant proof mass It is consistent with the book, but also provide the basis for future changes in the operation of medium quality monitoring. Means passing the tests of the gas-steam heat transfer fluids using pumps to transfer fluids within the furnace and the injection of hot expander. When pumps heat transfer fluid to the injection system, should check again the furnace, heating equipment, piping system drain valve, drain valve is closed, in order to avoid loss of heat transfer fluids. While the exhaust pipe and the valve opening on the furnace one by one, to exclude air, until a closed gas steam flows. It stops when the oil level gauge appears on the expander injection heat transfer fluids, and then start the circulation pump, for circulating cold. Existing gas steam oven dry dust, do not meet wet desulphurization process of flue gas CWS humidity, water vapor in the flue gas as coal-water slurry up to 36%, some as high as 40% or more water content of coal-water slurry, If we consider only the dust and sulfur dioxide that is not enough. Arts gas 6300 kw steam boiler company after multi-party experts to study, test, develop a dusting product, the successful use of coal-water slurry plenty of water in the flue gas as a carrier, by cooling, reducing condensation, dust and sulfur dioxide capture down, to achieve excellent results gas desulfurization steam oven. The effect of dust reaching the user's satisfaction. Gas welding gas steam oven must be operated by welders holding boiler and pressure vessel certification of welders. Welding dimensions meet the design drawings and process documents, bead height is not less than the base material, the base material with a smooth transition. Gas fuel gas steam oven weld and heat affected zone no cracks, holes, craters and slag. Weld undercut hole deeper than 0.5mm, the total length (the sum of both) is not more than 1/4 of the circumference of the tube, and not more than 40mm. Construction of gas steam oven strict compliance with welding procedures and other relevant standards and regulations, and make construction records welded to record the record.
