coal boilers for greenhouses china
WNS type coal boilers for greenhouses china and gas boiler SZS What's the difference? After the state has increased in recent years, efforts to manage the environment, improve air quality, all walks of life are generally boiler retrofit or replacement gas boiler became a coal-fired boiler, the implementation of coal to gas boilers in large-scale, often encounter some customers when purchasing gas boiler, except consulting WNS type boiler and gas SZS type gas boiler, which both thermal efficiency higher? Now, I give you a brief overview about the difference between the two.
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.
In modern industrial production, the coal boilers for greenhouses china plays a very important role, but it is also easy to scale or suffer corrosion damage. Therefore, boiler heaters need to clean the relevant boiler equipment in time under this condition, in which the non-cleaning agent which has the most outstanding performance and practical effect is the non-cleaning agent. When the heating system is replaced, cleaning agent must be used to clean the pipe to eliminate the inner wall debris so as not to affect the heat transfer efficiency and service life. In use, it should be carefully checked, water-proof, acid, alkali and low boiling point leakage into the use system, and add a filter device to prevent mechanical debris into the system, to ensure that the oil is pure. Degree According to the requirements of the grade and the heat use process, all kinds of high temperature brands are selected correctly, and the regulations of the Safety Technical Supervision rules for Organic Heat Carrier Furnace are strictly complied with, and they are used correctly. The high temperature of boiler is suitable for heating equipment such as coal burning, gas, fuel oil heating furnace as carrier, electric heating reaction kettle and other heating equipment, such as expansion tank, oil storage tank, other safety components and temperature control instrument, etc., so as to ensure safe operation. The purpose of the boiler cleaning agent is to quickly remove the dirt and carbon accumulated in the internal pipes and heat exchangers of the boiler. Then we also have requirements for cleaning agents. We must not harm our metals. Heat transfer surface, requires no residue, complete dissolution, and must be easy to operate, as long as ordinary personnel in accordance with the use of procedures on the operation. The requirements of our Fangkuai boiler for boiler cleaning agent are: low energy environmental protection, five poisons odorless, non-flammable, small irritability, can be discharged directly after cleaning.
1, compared to the traditional coal-fired coal boilers for greenhouses china, gas boiler higher cost low nitrogen
Conventional coal-fired boilers is generally filled manually directly into the coal combustion furnace, this method results in very large combustion sulfide, soot and other harmful substances discharged into the atmosphere pollution index high; but also need to manually plus fuel, time-consuming and labor-intensive, more harm than good.
