March 11, we learned from the Harbin municipal government: Harbin win the 2019 New Blue Sky Battle embodiments released this year, Harbin will be coal-fired pollution control, pollution discharge standards, high Vehicle emission control, comprehensive improvement of urban and rural non-point source, and prohibiting straw utilization as the main direction, precise Shi policy. Strive to the end, so that the sulfur dioxide, nitrogen oxide emissions are reduced by more than 17.6% in 2015 and 20%; concentration of PM2.5 decreased to 52 micrograms / cubic meter or so, and strive to 50 micrograms / cubic meter or less; and more severe reduce the number of pollution days to 21 days or less.
After the proposed scheme, Harbin bulk coal strengthen management and control, strengthening coal quality testing, to improve the sampling frequency. This year will develop clean heating embodiment, the priority development of the city urban central heating; central heating covered areas being difficult to accelerate the implementation of natural gas heating and electric heating, and other distributed clean heating. Unit embodiment "coal to clean energy" should be synchronized removal of coal-fired boiler, gas boiler need replacement after low NOx combustion technology, clean heating rate of 60% or more. City buses, taxis or car clean energy proportion of new energy and strive to reach 94% and 80%. Promote the use of gas vehicles to achieve the national emission standards for six. Six to stop selling below the country's gasoline and diesel. Establish responsibility dust control system, built-up areas prohibit the construction site mixing of concrete, mortar and use of bagged cement 9 city and county (city). Under the premise of protecting people's livelihood, heating boilers should be relatively conducive weather conditions during the pollutant dispersion from the oven, in the same area by different heating boiler early in the evening three periods of peak load shifting from the furnace.
How to determine the steam pressureless boiler plant accident occurred less water? When the water level is less than the minimum water level has been defined, but the water can still be seen in the gauge water level, slightly less water is determined; when the water level can not see the water meter, it is judged severe water shortages. Status summarized in the following: a conventional water level (1) is less than the height of drum level defined; (2) low level alarm, automatic warning sounds, warning light flash from; (3) superheating steam temperature increases; (4) Enter water is not a conventional, inferior steam flow rate value; (5) the flue gas discharge temperature.
Classification and use of electric pressureless boilers electric boilers, also known as electric water boilers, electric water boilers, electric tea stove, electric stove, boiler and into a continuous subdivision two kinds of electric water boiler electric water, in order to meet more people drinking water the needs of design, development utilizing electrical energy into heat production of drinking water equipment, mainly for schools, hospitals, factories, supermarkets, shopping malls and other population-intensive units. The main components of electric water heaters from the heating effect of the electric heating tube, the best choice for separation of water and electrically insulating ceramic material of heating tube, heating the tube such high safety, long life, typically up to work under normal circumstances 6 -7 years. Electric water boiler, also known as electric heating boilers, electric heating boilers, electric heating boilers, electric boilers bath, electric bath boiler, electric water boiler is using the latest technology and electric control system design to complete production of hot water, heating or supply to meet life, bath automatic green boiler with hot water. Such boiler is suitable for a wide range of hotels, villas, factories, office buildings, government agencies, universities, hospitals, military and other appearance requirements for domestic hot water heating and high places. The electric boiler is divided into direct thermal boiler and electric boiler electric thermal storage type two, direct thermal electric boiler as the name suggests there is not more to explain, regenerative electric boiler is based on the power sector to encourage electricity in peak hours heating, and enjoy preferential tariff policies, the introduction of a new, energy-efficient electric heating products. Storage electric boilers together with the heat storage tank and ancillary equipment constitutes a system storage electric boilers, heating with hot water in the storage tank, and to achieve the full use of the low power or low power head to part. Electric steam boiler it is also called electric steam boiler, steam boiler power by the power supply means to heat the steam boiler and produce rated pressure. Electric steam boilers can be used in textile, printing and dyeing, paper, food, rubber, plastics, chemicals, pharmaceuticals, iron and steel, metallurgy and other industrial products machining process required steam, and for enterprises, institutions, hotels, schools, restaurants, services, etc. industry heating, bath, air conditioning and hot water.
What types of pressureless boilers manufacturers have? Although the boiler is all very common type of equipment but most people understand the extent of the boiler is not deep, because the boiler in layman's view similar in appearance, but in fact many different types of boiler boiler manufacturer can produce, and the type there are different characteristics and adaptability.
