Method for implementing energy saving and environmentally friendly features a method of environmentally boiler boiler: the boiler flue gas heat recovery boiler is an important way of saving large flue gas calorific value, only the latent heat of vaporization of water vapor is sufficient to boiler feed water is preheated to above 100 ℃ not only can be used for boiler feed water, the excess water can also be used to heat domestic hot water. Fuel, boiler exhaust gas heat loss of about 8% to 16%, about 1% heat loss sewage, furnace heat 1 to 2%, 1% incomplete combustion, effective utilization of heat of about 80% to 91%, the flue gas includes N2 accounted 68%, Co211%, H2O16%, O24%, SO22PPM, NOx80PPM. If the exhaust gas temperature of 200 ℃, high total heat recovery through the heat exchanger, flue gas temperature can be lowered to 70C or less, the boiler feed water to raise to 20 ℃ 85 ℃, saving a lot of energy. Meanwhile, since the oil and gas, especially natural gas sulfur content less, the content of SO2 in the flue gas is very low, most of them are dissolved into condensed water discharged flue gas, the combined flue gas heat recovery devices are made of stainless steel, to ensure a reliable means corrosion resistance, and therefore the service life of the entire device more than 5-6 years. By monitoring, the indicators have reached the national environmental standards. Environmental regulations described boiler drum assembly welds should be: the drum longitudinal and circumferential weld head assembly or assembly welding seam characteristics weld two elements should satisfy the following requirements: the longitudinal weld seam or stitching head deviation of the actual edge on both sides of the steel sheet is not greater than 10% of the nominal thickness, and not more than 3mm; when the thickness is greater than 100mm, of not more than 6mm. Deviation of the actual edge seam on both sides of the steel sheet ring is not greater than 15% of the nominal thickness plus 1mm, and no greater than 6mm; when the thickness is larger than 100mm, no more than 10mm. Two abutting element or plate have different thicknesses and the edge of the book cut, treated according to the same plate thickness, the above-described nominal sheet thickness means; butt plate of different thicknesses, but with no thinning, the nominal thickness of the aforementioned finger planks . Any difference between the maximum inner diameter of the same cross-section and the minimum inner diameter of the drum should be not more than 1% of the nominal inner diameter. Angularity drum longitudinal seam should be no greater than 4mm. If the pressure detecting element via a weld joint defects found unacceptable, welding unit shall find out the reason, the development of a viable repair program to rework. Before welding defects should be completely removed. After welding, welding zone should be done appearance inspection and nondestructive testing. Heat treatment after welding element requirements, should be done after the welding heat treatment after welding. Rework the same position should not exceed three times. Repair parts, frequency and circumstances shall be deposited in the boiler repair product technical file.

A strict boiler installation access. For newly installed boiler strictly enforce provincial and municipal environmental policy, a full cessation of 35 tons and below, installation and construction of coal-fired boilers to inform, installation supervision, inspection and use of registration, to cooperate with the elimination (dismantling) work.

Second, the coal-fired boiler using a registration certificate cancellation notice. According to regulations, the original registration for the 83 and 10-ton coal-fired boilers using the write-off registration certificate shall be published on the government website, while informing the inspection unit will not be tested.

Third, strengthen supervision and law enforcement boiler safety, to promote the phase-out of coal-fired boilers. The boiler safety supervision and law enforcement with prevention and control of air pollution combine to crack down on illegal installation of boilers, illegal use, not extended inspection, not extended rectification risks and other illegal acts, to perform their duties according to law, to promote the phase-out of coal-fired boilers smoothly. This year we have gone through all kinds of boilers 117 units, of the 10 units are still using coal-fired boiler inspection found, ordered to stop using and timely communicated to the relevant environmental authorities and the town street, cooperate with the 10 coal-fired the dismantling of the boiler.

Although the fuel of 58MW circulating fluidized bed 0 7mw hot water boilers price is also coal,but it adopts CFB circulating fluidized bed combustion technology,and mixture of gas and solid, and the fuel particles and circulating combustion, the fuel particle residence time in the furnace is lengthened, the combustion efficiency can reach 97-99%. The boiler thermal efficiency up to 85%, higher than the national standard of 15-20 percentage points, has remarkable energy saving effect and economic benefits. In the society to reduce the energy waste, but also to reduce dust emissions, the social benefit is great.

Oil-fired boiler work and preparation before purchase if necessary fuel boiler induced draft fan, this is a particular kind of boiler, and all of us concerned, but also need to have a comprehensive knowledge and understanding, so as to know how to correct and rational use of oil-fired boilers this a boiler at the same time to achieve the purpose, can also increase their expertise in this area. Whether to do some preparatory work before 1 oil-fired boilers to buy? Oil-fired boiler product before making the purchase, it is the need to do some preparation work. Moreover, this work has two purposes, first, the importance of this work reflects the product purchase, and second, to avoid the wrong choice appears. In the specific content of the work, first have a clear understanding of the environment and the requirements of the product, the second is some basic information to understand the product and production manufacturers, including product origin, specifications, size, performance and technical parameters, product quality and price and product service, in the process of considering these factors are indispensable to ensure accurate judgments and the correct choice. 2. Fuel different classification criteria boiler Are there different kinds? Oil-fired boiler, which is a specific kind of boiler, so, as with a normal boiler, at different classification criteria corresponding to different species, therefore, the answer to this question is yes. If the kind of fuel according to points, can be divided into two oil-fired boilers and boiler heavy gas oil boilers, diesel or gas oil refers to the kerosene, heavy oil is extracted by means gasoline or diesel oil as the rest of the heavy oil. In addition, the boiler according to purpose to points, can be divided into a fuel oil-fired boiler water boilers, 0 7mw hot water boilers price fuel, heating fuel boilers, boiler and fuel oil bath and steam boiler these. 3. The oil-fired boiler fuel consumption calculations it important? From a professional point of view, to calculate oil-fired boiler fuel consumption is very important work, and careless treatment can not be ignored, because if get the wrong result, it will affect the normal use of the boiler. In addition, we also need to know is that there is a corresponding formula, under normal circumstances the use of boilers, boiler output if different, then the boiler fuel consumption is not the same. 4. Does fuel boilers must have induced draft fan? There are requirements for the quality of its oil do? Whether fuel boilers must have induced draft fan, according to this aspect of professional presentation, the answer is not necessarily, because depends on whether the specific circumstances so require, if the amount of air supply and flue fuel ratio appropriate and clear then use the blower can be. This kind of boiler oil-fired boiler, its oil quality is not clearly defined requirements, but in the use, certainly requires better quality fuel, so as to ensure the boiler work properly.
