In recent years, Ningbo municipal government attaches great importance to environmental protection, air pollution prevention and control work to strengthen the organization and leadership, the establishment of a multi-sectoral collaboration to air quality at the core of the atmospheric environment management systems. And introduced a new quality of atmospheric environment deadline for compliance plan, as follows.

Strict implementation of total coal consumption control, to further optimize energy consumption structure, strive to 2020, coal consumption accounts for the proportion of primary energy consumption control in about 40% of coal consumption is not higher than 2011 levels, and completely cut coal province issued the task .

Strengthen management work focused on coal-fired projects, continue to promote the elimination of the transformation of small coal-fired boilers. 2019, phasing out 10 steam tons / hour of coal-fired boilers and, in 2020, the county level and above urban area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically eliminated the city's 10 -35 steam t / h coal-fired boiler; 35 t steam / hour and more polluting fuels and ultra-low emissions energy boilers complete transformation.

Strengthening coal quality control, within the city limits the use of ash> 16%, sulfur> 1% low-quality coal, fuel encourage high value, low sulfur, low ash blending works. 2019, the establishment of the city's coal regular testing, sampling tests system. In 2020, the city's clean coal utilization rate of 90%.

Increase natural gas use, and actively promote major infrastructure construction official website of natural gas, LNG receiving station and other utilization of natural gas, natural gas Daly improve utilization levels.

Enhance the energy efficiency of industrial enterprises. Actively promote advanced energy conservation projects integrated coal demonstration projects, large-scale generating units coal consumption reached the advanced level of the same type of unit.

Development of central heating, central heating project to optimize the layout, promote industrial parks focused on central heating. Focus on industry gathering area, industrial park development of cogeneration, and encourage qualified development of thermoelectric cooling area for the triple. Further improve the matching of heating pipe network, construction of efficient, fast heat pipe network. 300,000 kilowatts and above cogeneration power plant 15 kilometers behind the small coal-fired boilers and coal-fired thermoelectric heating within a radius of all closed down integration.

Factors industrial boiler energy-intensive factors which have high energy consumption of industrial boilers which 1, energy consumption is low management level industrial boiler is too large, there are currently a lot of long-term business. On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.

What are the common type gas fast install horizontal steam boiler design have? Common types of gas steam boiler is as follows: fuel (gas) is oil or gas as fuel, burning the fuel using a burner to heat the gas as steam carrier. Structure is generally divided into two kinds of vertical, horizontal, mainly based on these two forms of device space height. Gas based on coal as fuel, gas and steam as a heat carrier. Hand generally divided into vertical burn, horizontal cylindrical type, three kinds of gas fired horizontal plane structure, mainly based on labor intensity stoker thereby form these three points. For electric heating electric heating oil furnace, heat is generated and transmitted by the electrical heating element is immersed in the gas and steam to steam gas medium by the circulation pump to force liquid recycle gas steam, with a heat transfer to or more heating equipment, heating equipment after unloading, re-circulation pump, back to the heater, and then absorb heat, heat transferred to the device, again and again, to achieve a continuous heat transfer the temperature of the heated object rises, the heating to achieve process requirements.

When the weather gets colder and colder, people will choose different ways of heating, one of which is more convenient is the fuel-fired boiler, but many people do not understand his use, so take a look at the following. Classified oil-fired boiler is a kind of boiler with many kinds of oil such as diesel oil, waste oil and so on. Its general structure and arrangement are similar to coal-fired boiler, and the common classification is mechanical type and steam materialized type. The characteristics of the bottom of the oil-fired boiler are to make the bottom of the furnace inclined to the back wall, which is the bottom of the heat preservation furnace, in order to obtain good combustion characteristics. This kind of boiler, for those who don't have a natural gas pipeline, Hope the boiler can run normally low cost, then the fuel-fired boiler is a very good choice. The fuel-fired boiler is an important symbol of the progress of the times, in order to serve the human being well and further perfect according to the needs of the people. Oil-fired boiler is designed in accordance with certain commercial standards, to a certain extent to ensure the excellent boiler, but also to a certain extent to improve the heat absorption strength of the boiler, then how should we use it? Design problems according to the oil-fired boiler inside the design of the boiler inner tank is larger, can store steam will be corresponding to more, suitable load capacity will become stronger, can be To meet the needs of different users, the cleaning of internal gall is also more convenient. The fuel-fired boiler with fire tube structure adopts the structure of triple-reflux fire tube, and the flame burns in the combustion chamber with high thermal efficiency, energy saving and consumption reduction, so it is economical and convenient to use. According to the unique design of the boiler, the use of the oil-fired boiler needs to find a set of operation steps suitable for the boiler and give full play to its function.
