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.

Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Hot water boiler water filling boiler considerations and parameters between boiler pressure hot water boiler of this kind in which the boiler is a common and frequently used species, but also in terms of all of us, need to have a comprehensive knowledge and understanding, because the only way to be correct and rational use of hot water boilers and have good results, but also to avoid misuse and adverse impact. 1. boiler parameters, whether on the same hot water boiler and steam boiler? From a professional point of view, the parameters of hot water boilers and steam boilers are not exactly the same, there are some differences, because the parameters of the boiler steam boiler steam boiler is concerned is the number of generated operating pressure and temperature steam, hot water thermal power boiler in terms refers to the boiler, the water supply and return water pressure and temperature. In addition, its different parameters, it corresponds to the unit is not the same. 2. Boiler Feed water pressure Cautions Boiler Feed pressure hot water process, there are some considerations, which is specifically as follows: (1) Sheung boiler heating system should be carried out separately, can not be together, because the boiler when you stop running between the boiler and the system is cut off. At the operational level, is you want to Sheung Shui to low water boiler expansion tank, then the system can Sheung Shui. Water Supply System, which can be used to perform Sheung pressure of the water filling the water system, if the pressure is less than water, circulating pumps can be used for water filling system. (2) If the system is filled with water by the circulation pump, which is specific to the operation: the boiler return pipe inlet valve is closed and the circulating pump will be multiplexed into the water pressure in the system until the system after the completion of charging water, then adjust the water level in the boiler. Meanwhile, while the system is filled with water, to be noted that the exhaust gas system. 3.1.4MV electric heating hot water boiler, heating area which is how much? 1.4MV electrically heated hot water boiler, its heating area is calculated, it needs to know the required heating power per square meter, heating, boiler pipes and boiler efficiency loss of these parameters, in order to obtain specific numerical values. If the heat required for heating power per square meter is 80W / h, boiler conduit 20% loss, then, the electrically heated hot water boiler heating area of ​​10,000 m2. However, this is the theoretical value, there may be some discrepancies with the actual value, without taking into account other external factors in this case.

Use hot water boiler should pay attention to security issues, especially hot water boiler electric boiler there are many security problems that require attention, in the course should be noted that some of the security detail during use. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees hot water boiler assembly PC-style water boiler controls, all functions are stored on a smart chip to achieve intelligent, digital boiler, automation, humane, intelligent control of boiler water temperature, water temperature reached the heating automatically stops; large screen font display water temperature, boiler water temperature at a glance. Running hot water boiler, must comply with the provisions of wearing clothes, carefully check the various parts of the boiler system, such as pressure gauge, safety valve, supply pipe accessories, such as water level, before continuing to work. When water, when the water to a predetermined level, we must be careful not to single-handed operation, one hand open valve injection machine, turn off the water valve before closing the valve. This order is not reversed, when the steam valve is closed, the surface not facing the surface. Against water splash hurt face. When the boiler has to work, someone must guard time water level and pressure gauges, must not neglect their duties. If you work late, you have to have a good rest during the day, so you will not doze off at night. Because if there is anything careless, it will be an accident. Boilers must exhaust every night, every night to clean up the water level gauge. Motors and other mechanical equipment should be regularly checked, if found any exception, should be checked immediately. Check the safety valve of the week.
