According to instructions, "Neijiang City in 2017 and phase out coal-fired boiler desulphurization facilities construction program of work", before the end of this year, the city built-up area will be fully phased out in Neijiang City, 10 steam tons / hour of coal-fired boilers and a total of 46 units. Among them, a small city in district out of coal-fired boilers 26, and phase out coal-fired small boilers Dongxing District 15, Neijiang Economic Development Zone small coal-fired boilers out of five. At the same time, accomplish four Chuansha Qi Industrial Co., Ltd. Two 20 tons of steam / hour or more coal-fired boiler desulphurization facilities. A ban on new urban area 20 steam tons / hour of coal-fired boilers, other counties (cities, districts) in principle, the new 10 steam tons / hour of coal-fired boilers. Out of the way including demolition scrap, coal to gas, coal and electricity upgrade boiler swap with large capacity.

We understand that the new Neijiang 20 tons of steam / hour for coal-fired boilers built-up areas, the new 10 steam tons / hour or less fixed asset investment projects in other areas of development and reform, economic and information technology departments will not be approved, approval and filing, environmental protection departments at all levels shall not pass environmental impact assessment, quality supervision departments at all levels do not accept the installation told not arrange supervision and inspection, no special equipment issued registration certificate. Quality supervision departments at all levels cancellation of special equipment for the boiler has been out of use registration certificate to prohibit the production of boiler manufacturers boiler does not meet industrial policy.

Gas-fired steam boilers of different types and their advantages on the common market gas steam boiler model, what does? According to data accumulated over the years, the statistics, the results are as follows, for your reference to understand. WNS fuel gas steam boiler, low cost, the implementation of the pipeline, so that lower gas prices, fuel cost decreases; the model of high boiler combustion efficiency, fuel savings, investment buying low fuel costs; the whole side pull butt welds, boilers the use of safe, long life, low maintenance costs. High efficiency, there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; using automatic burner, water continuous electric adjustment, high combustion efficiency. SZS fuel gas steam boiler, with international popular three-pass shell type, all wet back structure, large volume combustion chamber design, burning more fully. Internationally renowned burner, combustion chamber all-corrugated furnace structure, both to strengthen the flue gas disturbance, but also increases the radiation heat transfer area. Not only increases the stiffness of the furnace, and effectively weaken the expansion stress of the furnace; enhance both heat transfer, but also to promote the fuel combustion within the furnace. Vacuum gas hot water boiler, high safety, vacuum boiler because the phase change medium flow system below atmospheric pressure, absolute pressure inside the unit is running is 0.02 ~ 0.08MPa, the unit is in a vacuum state, and thus the explosion does not occur. Long life, internal boiler fouling does not occur, increasing the life of the boiler use. Heat exchanger portion with stainless steel, corrosion-resistant, the design service life of 20 years. High degree of automation, the use of the control device and mechatronic joint control programmable logic controller. Long life, scientific product design, advanced processing technology and strict quality control, all factory production of boiler equipment. The advantages of gas steam boiler in recent years reflects the more comprehensive. Exacerbate air pollution causes the gas steam boiler into the market faster. Gas-fired steam boiler is a clean energy, natural gas fired industrial boilers, and with the traditional burning of fossil fuels such as coal boiler has unparalleled advantages in comparison. Natural gas boiler steam boiler market development trend in the future, the future market development of industrial boilers except by factors affecting the pace of development of our national economy and the scale of investment, etc. In addition, more and more restricted energy policy and energy-saving, environmental protection requirements.

Vacuum hot water boiler operating gas: a gas hot water boiler operating under vacuum: the vacuum gas hot water boiler utilizing the different characteristics of different boiling point of water at ambient pressure. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler operating pressure in the range -0.07Mpa less. Corresponding boiling temperature of water is less than 93 deg.] C, vacuum gas at the operating pressure of the hot water boiler, the combustion temperature rises to the water boiling temperature, the steam boiling surface to produce the same temperature, volatile vapors absorb large amounts of heat. At this time, water is injected into the heat exchanger of the boiler. After the inner tube was heated to an outer cold administered heated steam flows out through the steam pipe outside the cold water cooled heat exchanger is condensed into water droplets, the water cycle is completed in vacuo. 1. smoke tube was added in the process, improve the heat transfer effect of making the arrangement more concentrated. With a square overall structure independent spray, beautiful shape of the separation. three. Large furnace techniques: effectively increasing the heat radiation area of ​​the unit, to reduce the nitrogen oxide emissions. 4. Boiler water using a high water to ensure that water does not furnace fouling and oxidation. All wet back shell type three-way structure, static heating, excess heat .6, actively control the whole system, it does not require special duty. 7. Unique pulse level detection circuit reliable performance. 8. inlet / outlet temperature display easier to control the operation of the vacuum and hot water boiler operating segment. 9, receiving advanced multilayer insulated glass wool, heat loss is small. Vacuum gas hot water boiler with three pressure safety system: automatic safety explosion-proof valve in the discharge control: when the internal pressure of the boiler continues to rise, the explosion-proof valve due to EHV broken, releasing the pressure in the boiler, to ensure safe operation of the boiler; Digital Pressure Switch: imported from Japan digital pressure switch, detecting a change in the pot at any degree of vacuum, when the pressure is too high, side off: opening vent automatic safety alarm: the boiler when the internal pressure becomes slightly positive pressure, vibration proof safety valve automatic alarm , cut off the power boiler.

What oil-fired boiler fuel oil boilers are generally burn diesel fuel, as well as specialty boiler fuel oil, black oil. But because diesel prices gradually rise and supply problems, and now are turning to fuel oil. (1) Crude: mined from below the ground, dehydrated, without refining petroleum. Crude oil can be refined and a variety of other products, directly as a fuel is extremely fair. (2) heavy: by cleavage of heavy oil, heavy vacuum reduced crude oil or a wax obtained by modulation in different proportions, certain grades and quality standards. (3) residue: residue in petroleum refining process, it may be treated directly as fuel supplied to the boiler, called the residual oil or oil residue diet. The main varieties are heavy and residual liquid fuel for power generation, the common features are: larger relative density and viscosity; flash point and a higher boiling, less volatile. (4) Diesel: Diesel is diesel fuel, as a boiler fuel is extremely economical. Diesel fuel generally used as a co-oil ignition and stable combustion pulverized coal boiler low load operation.
