Boilers which are several general, in what is now the mainstream Why? 1, gas fired vertical boiler manufacturer advantages: efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no transportation fuel, no need to deal with soot, due to the combustion of natural gas free of impurities, without corrosion damage to the boiler and related accessories long boiler life, defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Cons: You do not know how much that gas prices are calculated according to the calorific value and thermal efficiency, generally bituminous coal per ton of coal (according to 5500 kcal / kg) is approximately equal to 350 to 400 cubic meters of gas. Probably a little slightly more expensive than coal. (No transport, area, ash handling, labor, etc. into the calculation). 2, oil-fired boiler, advantages: substantially the same structure and properties of gas boilers. Disadvantages: higher cost of natural gas is 2 times the boiler, diesel transportation, storage more dangerous, accident-prone. And the domestic diesel supply is unstable, easily interrupted. 3, coal-fired boilers, the advantages: the economy. Disadvantages: 1, requires a lot of ash and coal yard area. 2, a boiler fireman for 4 to 8 people. 3, boiler room and coal yard is very dirty. 4, noise, emissions of dust, nuisance. 5, environmental protection departments often to check an inattentive, he was diagnosed with excessive emissions, maintenance shutdown, fine, very troublesome. 6, coal sulfur content are more severe corrosion of boiler, 10 to 15 years after the basic unusable. Summary: Due to high oil prices and supply unstable now, and now oil-fired boiler has been temporarily withdrawn from the market. Natural gas prices due to regional differences are very different, although you are not sure where the price of natural gas, but natural gas in most parts of the domestic coal is relatively expensive, (only in Sichuan, northwest of cheaper natural gas). Especially large industrial boilers, more fuel, the cost difference is more obvious. Coal-fired boilers to heavy air pollution, with the country on environmental issues more and more attention, more stringent emission requirements for coal-fired boilers, a lot of urban cities, has stopped the examination and approval procedures coal-fired boilers. It is recommended that, if your organization is not large tonnage production of boilers, installation of gas boilers or better, although with a little more than fuel costs, but in the actual operation of the process, you can save a lot of things, while saving area, the environment is clean.
According to statistics, Zhejiang Province, coal consumption totaled 145.91 million tons, accounting for 56.8% of primary energy consumption in the province. Although after careful environmental management, but the main coal-dominated energy consumption remains high in the province's total emissions of air pollutants. In the "Zhejiang Air Pollution Control Action Plan (2013-2017)" issued in December 2013, the coal-fired pollution control remains a top priority.
According to "Zhejiang low-carbon development" Thirteen Five "plan", as of 2020, the province's proportion of non-fossil energy sources will be increased to about 20%, the proportion of the total coal consumption should be reduced to around 42%.
June 15 this year, Hangzhou Iron and Steel Group ironworks blast furnace in the chimney successful blasting, declared the "three noes" no way to urban development of Hangzhou steel companies, no coal-fired generating units, there is no standard yellow car.
To control pollution from coal-fired source, Zhejiang Province, facing elimination from the transformation of the boiler parties policy, funding, pricing, comprehensive resources supporting the work in 2015, 2016, 2017 were given every right out of steam coal-fired boilers tons 15,000 yuan, 12,000 yuan and 10,000 yuan subsidy funds.
To eliminate 10 tons of steam / hour of coal-fired boilers, in October 2014, Zhuji City, party and government "leaders" personally took, within three months, through the introduction of reward and subsidy standards, regular assessment and other measures, the city's 1964 stage production behind coal-fired boiler demolition 1508 units, 390 units to natural gas or electricity, and the rest use biomass fuel, gas tank or centralized heating, completed the task of transformation. It is estimated that, this year more than 500 tons of sulfur dioxide emissions.
After a clear goal, the province's coal-fired boiler (kiln) transformation to accelerate out of the furnace. According to statistics, in the first half of this year, Zhejiang Province eliminate small coal-fired boilers 6200 Taiwan, has completed 77.5% of the annual task of eliminating.
2.1MW horizontal gas-fired thermal oil heater for chemical industryThe dyeing auxiliary is a chemical which enables a processing operation in textile preparation, dyeing, printing or finishing to be carried out more effectively, a fired vertical boiler manufacturer provides stable heat source for its production process. Wuxi Kailai Biotechnology Co., Ltd., established in 2001, is an enterprise specializing in developing and manufacturing textile dyeing auxiliaries. The improving performance requirements for textiles lead to a largely increasing demand for dyeing auxiliaries. Kailai Biotechnology decided to obsolete the backward productivity due to the need of enterprise's own development as well as complying with the policy requirements of environmental protection, Kailai Biotechnology planned to order one set of 1.8 million Kcal thermal oil heater and use clean energy natural gas as boiler fuel.As one piece of important equipment of the production line, the thermal oil heater has a direct impact on the quality of dyeing auxiliaries and the benefit of the whole enterprise. After a series comparisons of boiler suppliers, the director of Kailai Biotechnology was deeply impressed by the large-scale, specialized and fine production of ZOZEN.Taking the actual working conditions of Kailai Biotechnology into consideration, the sales manager of ZOZEN provided one set of YQW series gas-fired thermal oil heater (YQW-2100Q) for the company. This series of thermal oil heater is equipped with an advanced low NOx burner, managing to ensure the full combustion of fuel and the NOx emission below 30mg/m3 ; in addition, the thermal oil heater adopts closed cycle heating, which has the characteristics of less thermal losses and remarkable energy saving effect; in conjunction with the energy-efficient equipment installed for the tail flue gas, the thermal efficiency of the heater can reach as high as 95%, the thermal oil heater is not only energy efficient but also safe.
However, South Africa is not credited with having coal deposits and hence, may not be in a position to maximize the benefits as coal is not an indigenous resource. By their own admission, SEG would import the coal from overseas (some have suggested that coal would be imported from South Africa) into South Africa and further transport it to the plant to be “burnt” in South Africa. This admission and subsequent action means that there is a beneficiary from the importation of coal. Given Zhengzhou Boiler ( Group) Co. Ltd credentials as a China-based company principally engaged in power plant fired vertical boiler manufacturers, supply of gas and development of all types of energies as well as researching and investing in new energy-related technologies, I find it hard to believe that coal would be consistently and sustain-ably sourced from other countries excluding China during the entire life time of the project because (1) SEG’s has credential as a major stakeholder in coal-fired power plant and (2) China tends to ensure that we source items from them in their attempts to assist us developmentally. All these and more suggests that the benefits of this project ensure more to China.
