New design good quality horizontal 2 ton diesel fired steam boiler
For this boiler, the capacity of the boiler is about 30m3, the capacity of pipes and heat exchangers is about 40m3, the total water capacity is about 70m3, the rated circulating flow rate is 200m3 / h, and the boiler replenishment rate is 1% of the circulating flow rate of the boiler. The actual recharge rate is 5 ‰ of the circulating flow rate of the boiler. According to the calculation of the actual replenishment rate, the boiler is heated in winter and the running time is 120 days. Then, the actual replenishment water amount is V: V=200m3/h × 5 ‰ × 24h/d × 120d=2880m3 (4)
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.
What are the implications boiler heat storage ability to run regulation? When the external load variation, the temperature in the boiler and metal working fluid, the heat and other changes have occurred. When the end of the combustion so as to increase the load time to adjust steam pressure drops, the corresponding saturation temperature is reduced, a corresponding reduction in boiler water liquid heat, and the heat storage boiler water discharged at this time the metal will vaporize a portion of the boiler water itself into steam. These generate additional evaporation vapor pressure can play a role in slowing decline. Therefore, the slower the heat storage capacity of the larger the vapor pressure decreased. In contrast, when the same combustion conditions, load reduction of the vapor pressure is increased, temperature rise due to saturation, and will be a part of a metal working fluid stored heat, vapor pressure so that the rate of increase slowed. Therefore, the heat storage capacity of the boiler is beneficial to the stability of the operating parameters. However, when the boiler is required to actively change adjustment condition is changed firing rate, the boiler load, pressure, temperature, heat storage capacity due to slow changes, can not quickly adapt to changing conditions.
Detailed introduction of oil-fired boilers
Oil-fired boiler (oil-burning boiler) is a fuel-fired boiler, including diesel oil, waste oil and other boilers. The overall arrangement of the oil-fired boiler is similar to that of the coal-fired boiler, except that the bottom of the furnace of the oil-fired boiler is mostly made into the bottom of the insulation furnace with a tilt to the back wall of 10 °~ 30 °, in order to obtain good combustion characteristics. In order to atomize fuel oil, there are two types of fuel burner nozzle: mechanical centrifugal injector and steam atomized Y type injector.
