To further reduce emissions of air pollutants and improve air quality of the environment, the Shanghai Municipal People's Government Office issued the "Opinions on accelerating the transformation of the city mentioned standard boiler hot water heater gas and electrics of small and medium" (hereinafter "Opinion"), to accelerate the introduction of Shanghai City small boilers mentioned standard transformation respond positively.

Before the end of 2018, the district in conjunction with boilers and industrial distribution block, complete the development and revision of the Gas Pipeline Network Planning in this area. City, district authorities, according to the unit Gas Pipeline Network Planning and excavation plan, speed up the construction of natural gas pipeline network.

Variety of boiler fuel to replace natural gas, natural gas pipeline network (municipal pipe network to users outside the red line pipe) 50% of the cost of laying borne by the gas company; the remaining 50% by the district government and users each pay half, and encourage qualified district to provide more support. On the outskirts of the gas pipeline construction is temporarily unable to reach enterprises in the region, while ensuring security compliance cases, it can be in the form of non-natural gas pipeline, and implement an orderly transition after the completion of the pipe network. Encourage alternative gas supply business enterprises to provide gas price discount for the gas boiler.

10KV for the implementation of alternative electric boiler, 35KV and other business expansion project, to which the power supply capacity of the electrical part of the boiler, according to the city's non-resident business expansion project quota standards, engineering fees charged by half.

Environment departments to strengthen law enforcement and inspection of boiler units, fuel use, operation and maintenance, equipment maintenance, inspection, non-functioning facility once found, according to the law severely punished; at the same time, strengthen supervision and monitoring, if it is found excessive emissions, according to law strict punishment.

Boiler units and boiler mentioned standard transformation service units bear the main responsibility for the boiler safety issues involved. Site construction unit must have the appropriate boiler manufacture or installation (reconstruction) qualification, boiler commissioning personnel must have the appropriate special equipment operator certificate. Prior to the construction site mentioned standard boiler units to implement the transformation, boiler location should be informed in writing of special equipment regulatory authorities.

The district government is the responsibility of the main boiler to mention the transformation of the standard, according to the "ground principles" to promote the transformation of the boiler. Combined with the actual circumstances of the district reform implementation plan, accelerating the construction of facilities to ensure timely completion of the task of transformation, to ensure that policies and financial support in place.

Gas boiler hot water heater gas and electric precautions required during installation methods, or steps :( a) a foundation base of the boiler should be provided is determined according to the local soil, manufacturers design reference by the civil sector again. After reaching the base strength boiler, the boiler should drawings inspection and acceptance, and to draw the whole boiler three reference lines: a, longitudinal reference line - drum center or the center of the combustion apparatus. b, lateral reference line - the center of the front axle or chain grate slag centerline of the machine. C, elevation reference line - can be selected from a number of locations about four weeks, respectively, on the basis of the marking, the relative offset between the markers should not exceed 1mm. Furnace in place. After assembly the lower part of the boiler in place first, then the upper assembly large, the upper and lower portions need to find a combination of two positive pads firmly, should be both inside and outside the two casting. Installation location and size deviation test methods according to GB50273 "boiler installation engineering construction and acceptance" implementation. (B) lifting the boiler, during lifting, should be suspended on a lifting lug drum boiler ready large, the boiler on a foundation base coincides with the pre-drawn reference line. The longitudinal centerline of the boiler and the foundation, the deviation is not more than 3 mm, and the inclination with the center line of the drum hammer correction, allowing the central drum inclination is not larger than 5 mm, otherwise use horns foundation base and the junction pad level. Maximum level (c) Installation of boiler network (1), water supply conduit installation requirements typically require as backup pool below the normal water level line of the boiler, so as not to shutdown, boiler feedwater flowing into a large number of drainage caused to start the next . At the outlet of the tank (i.e., an inlet feed line) should be installed wire screen. (2), a main steam line installation requires the main steam lead pipe straight run section should be more than 0.5 m, the bending radius should be 4-5 times the diameter of the pipe, the trap should be fitted at the lowest line in order to prevent water hammer pipe, while to be reliable insulation. (3), the safety valve should be installed in the valve installation requirements after the hydrostatic test, the safety valve shall be fitted exhaust pipe, the exhaust pipe of the safety guide outside the boiler house, allowed valving the exhaust pipe. (4), mounting a lower water table level table downcomer must access a safe place, Hancock rotating flexible water table, not leaking, water table must be installed to the lighting device, easy to observe. (5), a pressure gauge mounting means so that when the scale gauge vertical plates, should be painted red gauge scale to show the maximum allowable pressure boiler, rotating flexible plug gauge, not leaking, water flow, pressure gauges insulation prohibited. (Iv) the boiler chimney installation requirements, when lifting the chimney, the chimney should be straight, horizontal direction lead length should not be too long, generally less than 5 meters, the height of the chimney should comply with relevant national standards. To add chimney rain cap, the weight of the chimney should not fall directly on the boiler chimney take over the host. Installation (e) combustion system: 1, according to the combustion system of FIG power line control circuit, a control signal line and the control line is electrically connected, the program should be installed reliable ignition and flame failure protection devices. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine.

3.Heavy industrial applications burning gas, oil, refinery gas, hydrogen and off-gas fuels.

4.Higher thermal efficiency levels are possible,Less tolerance for water quality calls for water treatment plant.

5.With totally automatic burner and full set of safety protection device, thus automatic safety operation can be guaranteed.

6.The heat exchange surface area of the boiler and the space for water and steam are large enough to make sure the boiler parameters are stable.

7.The rear section of such boiler is equipped with flue gas condensing and recovery device which can effectively control exhaust gas temperature so that to improve boiler thermal efficiency.

8.Adopts high heat resistance material as adiabatic layer which brings a good thermal insulation property; the outer shell of the boiler adopts pressed guard board which makes the boiler looks delicate.

9.Adopts packaged structure; the whole boiler is fixed on the steel base with strong rigidity. Such structure provides convenience for installation and transportation.

Installation and internal gas steam boiler hot water heater gas and electric induced draft fan of the basic structure of the gas steam boiler configuration and cited the difference between the internal structure of the gas boiler steam turbines, gas steam boiler with induced draft fan needs it? Can be equipped with fan, but depends on the type of boiler and burner models, different designs, different configuration, such as boiler combustion and pressurized combustion positive pressure, negative pressure combustion needs to Fan, the combustion pressure is also equipped with the induced draft fan . Gas-fired steam boiler price? I do not know the local fuel prices. Meanwhile, steam boiler tons of gas consumption to about 7 degrees, and tons of gas boiler steam power was insufficient. Other aspects of superior gas or gas, such as environmental protection, operating environment, repair and maintenance. Gas-fired steam boiler water is quite easy to detect what instrument? Gas steam boiler is necessary to detect the water hardness and the total alkali content, to use these indicators generally chemically very convenient hardness complexometric titration on the line. Of course there are specialized equipment, and many, hardness tester, portable hardness portable Taobao has sold analyzer. I always feel that consumed 6 tons of water, steam and water is water present as at the tri-state nature. Water states are: ice, water, steam. Consumed water into steam, which mass is not changed, the change in energy occurs therein. Specific concept tonnage evaporated ton of water for an hour is defined as a tonnage if you tons of water evaporation is defined as N N tonnage. The answer is yes, the tonnage of the boiler is arbitrary, as long as you can do the right boiler design any tonnage. The difference between gas steam boiler and boiler construction of fuel gas steam? Because of the different fuels, have the following differences: a burner fuel steam boiler, gas boiler, the combustion method of a fixed grate, and a fluidized bed furnace pulverized coal burners and the like.
