household natural gas steam fire tube boiler

The use of electric steam household steam fire tube boilers What are the requirements? General Electric steam boiler is to be converted into an energy form of heat, through the conversion of the boiler can be turned into heat energy of steam or hot water, which requires the use of gas when you have it steam boiler, steam boiler in the first before water is necessary to check each valve, steam pipe, pressure variations, water tables, etc. also note the drain valve is not also intact. after the steam inside the boiler should be kept clean to be used, to which water is after softening the outer glass tube in the water table to be equipped with rugged protective cover, but also to keep it clean after each use it is necessary to scrub, as well as to see the water level of the water table there rise or fall, if it stops phenomenon, we must immediately investigate the cause. after the adjustment is not just above the steam boiler safety valve.

The working principle of steam household steam fire tube boiler steam boiler with boiling water almost equivalent to pot kettle, oven stove equivalent. Boilers and boiler furnaces is divided into two parts, the pot is filled with water to a metal container, partially combusted fuel furnace, the heat absorption of the water inside the pot furnace fuel combustion converted to steam. Popular terms, the steam boiler is to absorb combustion heat of the fuel into the water some parameters (such as pressure, temperature, etc.) of the steam device. For example, everyone knows to pulverized coal, for example. 1. The operation principle (an example in pulverized coal fired boilers) in heat pulverized coal combustion furnace, radiative heat transfer is first absorbed by the water wall, the Wall Boiling water, a large amount of steam into the drum for steam separator (DC furnace excluded), the separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2. Pulverized work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small; also affects the position of the center of the flame superheated steam or reheat steam temperature, generally lower the center of the flame in particular superheated steam reheat steam temperature to be low, otherwise higher. 3. The arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion.

Recently, Xi'an, Shaanxi Province take minus coal, train control, dust suppression, government sources, prohibiting other measures, the air pollution caused by human factors reduced to very low, efforts to improve air quality in Xi'an winter. As of early November, Xi'an has cut 100 million tons of coal-fired, 15 high-ranked companies relocate or shut down.

In 2018, the Shaanxi provincial government issued a formal mandate to inform, Xi'an total of 140 million tons of coal to reduce the task, mainly around the Xi'an city government to cut electricity, central heating boilers Chaigai, urban and rural residents scattered coal and gas supply security in four areas of governance to carry out jobs. As of the end of October this year, has cut coal 1.015 million tons, completed 70.7% year plan. Built area of ​​29,419 catering units are the use of clean energy, outside built-up area 5196 catering units are to switch to clean energy.

Vehicle exhaust is one of the sources of atmospheric pollution. In order to strictly control the "black tail", environmental management staff at the three-ring along the line, passenger stations, farmers market, food stores and other black smoke high incidence of vehicle checkpoints set up 423-bit, low-speed vehicles investigated a total of 71,300 cases to go cut the line , black smoke car 7027 cases.

In the "anti-summer period", Xi'an continue to implement the motor vehicle limit line of control measures, and completed the 3255 update of pure electric buses put into operation, the completion rate of 102%. Newly started construction of public parking spaces 12,908, 86.1% completion rate. Investigate ChaoBiaoChe 3504.

In terms of the source rule, Xi'an cumulative Mopai "scattered dirt" Enterprise 21021 (including New West Ham), complete renovation 8163, completion rate of 38.8%; 15 high energy consumption, high emission enterprises to complete the relocation or shut down; 3399 Taiwan low nitrogen gas boiler to complete the transformation, the completion rate of 99.4%.

40 industrial enterprises complete control of volatile organic compounds, the completion rate was 88.9%; 26 224 restaurants and stalls point to install smoke purification facilities; 1259 spray paint auto repair business to complete in-depth treatment of exhaust gas, and all the installation of pollution control equipment independent meter; the Third Ring Road 336 gas stations outside the full completion of the transformation of tertiary recovery of oil and gas, and all the installation of pollution control facilities separate meter.

In terms of prohibiting, Xi'an completed summer crop straw comprehensive utilization area of ​​249.82 acres of mechanization, comprehensive utilization rate of 95.4%, exceeding the target task. At the same time, organized and implemented six acres and nine provincial and municipal straw utilization demonstration projects, compared with the provincial target increase of 12.5 percentage points; investigate and deal with the problem of black smoke burning from 457; 8 consecutive years of summer and autumn straw Jinshao to achieve "zero fire point" goal.

This year, the Xi'an handled a number of prominent air pollution problems. City of iron-fisted rule examination revealed a total haze to do all kinds of air pollution problems 1862, the city set up a team of 153 people to strengthen the supervision and inspection found problems common enterprise 6128, cross-check inspection found a total of 11,781 business problems. These issues are issued under the supervision of the list of issues to be reform.

Steam household steam fire tube boiler When should an emergency shutdown when the steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.
