manufacturer middle valve tankless gas water boiler

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.

Recently, Wuhan City, introduced in 2019 to embrace the blue sky action plan for speeding up the optimization and upgrading of industrial structure, promote the optimization of energy structure adjustment, implementation of transportation restructuring, deepen industrial pollution control and other tasks proposed solution.

Among them, in terms of optimization and upgrading of industrial structure, we will study and formulate more stringent industry access threshold, no new heavy chemical and paper industry projects within 1 km of the Yangtze River and Hanjiang River shoreline. Strict implementation of ecological protection red line, the bottom line of environmental quality, resource utilization on the line, environmental access a list of constraints.

In optimizing the energy structure, the city's ban on new coal-fired generating units, supporting the construction of new projects is prohibited owned coal-fired power stations, will not be new coal-fired boilers. Increase efforts to promote green buildings, new buildings full implementation of green building standards. In deepening the industrial pollution control, referring to Beijing and Xi'an subsidies, launched a comprehensive transformation of low nitrogen gas boiler. Before the end of 2019, the district completed at least 50% of the area within the low-nitrogen transformation tasks 10 steam tons / hour or more gas-fired boiler.

How to solve the noise problem electric boiler in life, noise pollution is more serious, say, watching TV sound on too high, affecting the rest of the neighbors; the dead of night, when suddenly a loud whistle and so on, as long as influence people to rest, study and work in sound, we call it noise. With the development of modern industry, environmental pollution along with produce, noise pollution is a kind of environmental pollution has become a hazard to humans. Noise and water pollution, air pollution, solid waste pollution is seen as four major environmental problems worldwide. In real life boiler is a very common industrial equipment, boilers and our daily lives. But a lot of work ordinary boilers because of the existence of objective factors that led to the smoke generated noise and emissions out of the life and health of the residents have had a great negative impact, there are many residents because of disturbing behavior boiler plant boiler plant to court . These phenomena we have to raise the importance of environmental protection function of the boiler. First of all, we should understand the harm of noise on the human body much, high-decibel noise will make people feel irritable, headaches, serious cause endocrine disorders, and even lead to insanity. So to eliminate the noise pollution caused by the boiler, the boiler fan noise processing technology is particularly important. When the boiler operation very noisy, more than people can afford decibels, but the temperature of the boiler flue gas generated very high, if the closed method will cause noise so that the device can not burn the heat inside the boiler important equipment. Therefore, noise reduction processing and energy of the boiler should be combined, as follows: The crossing of the induced draft fan and the blower into the inside the soundproof chamber, and then use them to ventilation ducts connecting the body and the boiler, the soundproof chamber walls and roofs carved small holes, while the mounting portion muffling apparatus. Control indoor blower silencer should be inclined to the direction of the boiler room, the air inlet is in this case windward position, to a greater heat production in the middle of the motor cooling channel. In this way the boiler during operation, the outside air can enter a soundproof room for replacement of the heat of the motor through the induced draft fan, and then keep the motor temperature is not too high. At the same time, soundproofed rooms and muffler noise reduction equipment also played a role, excess heat can also be recycled, reaching both energy saving and environmental protection effect. As long as the boiler solve the noise problem, then the boiler will have a good development trend, environmental protection boiler will get everyone's favorite.

Gas furnace gas and steam steam steam importance gas gas gas steam boiler steam importance furnace gas and steam must sample tests, measuring visual quality of heat transfer fluids, flash point, viscosity, acid, water, and carbon residue, and certificate of quality manufacturing plant to provide heat transfer fluids are consistent, but also provide the basis for future changes in the operation of medium quality monitoring. Means passing the tests of the gas-steam heat transfer fluids using pumps to transfer fluids within the furnace and the injection of hot expander. When pumps heat transfer fluid to the injection system, should check again the furnace, heating equipment, piping system drain valve, drain valve is closed, in order to avoid loss of heat transfer fluids. While the exhaust pipe and the valve opening on the furnace one by one, to exclude air, until a closed gas steam flows. It stops when the oil level gauge appears on the expander injection heat transfer fluids, and then start the circulation pump, for circulating cold.
