Boiler

How hot water boiler equipment selection softening boiler water softening object is to remove calcium and magnesium ions, reduce water hardness and avoid prolonged substandard boiler feed water boiler causes scaling, corrosion, burst pipes and so on. Then the hot water boiler softening equipment selection should be how to do? (1) To have a clear understanding of the customer's actual water consumption, water consumption, including water volume and per unit time. In order to facilitate a reasonable selection for customers. (2) understand the customer's frequency of water, the water supply is continuous or intermittent water supply, we must be clear in order to identify the customer water consumption. (3) Customer boiler to the environment. To the customer the boiler water to water quality testing, acceptance be put into use. Hot water boiler softening equipment, boiler operation process is an indispensable auxiliary configuration, for Therefore, when the boiler running smoothly, reduce the cost of manual maintenance, security, performance boiler has a relatively high contribution to the efforts in the selection, must be carefully considered, we must not be careless.

In combination with the natural gas boilers proportional control valve and the premix fan, not only to ensure excellent air ratio of gas, also automatically adjust the boiler output to meet the dynamic heat load, the heat output curve dynamic heat boiler demand curve as close as possible, without generating invalid outputs, heat exchange efficiency can reach 108%, the real energy saving.

Furnace heat loss is not the traditional unit fuel boiler, furnace purge caused by heat loss when the gas boiler ignition start. To ensure the shutdown, the safety of the ignition, fuel, gas boiler before ignition, must be shutdown after purging the furnace for about 15min, i.e. combustible gas with cool air blowing in the furnace. Thus the heat within the furnace is substantially consumed. In the early heating, the end to adapt to changes in load, inevitably frequent start and stop boiler, each will take away a lot of heat furnace. According to the analysis of heat loss due to the furnace purge due account for 5%, while atmospheric boiler module does not purge the furnace, there is no loss in this regard.

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.
