steam boiler applied in varies industries

Methods and characteristics of steam boiler applied in varies industries water treatment

The steam boiler water treatment method has the boiler outside and the furnace also called the pot inside and outside the pot. Generally, for steam boilers and steam-steam boilers larger than 2t/h, the chemical water treatment outside the furnace should be adopted as far as possible, on the other hand, the steam boiler can only be treated with medicine in the furnace, but other means should be adopted to ensure the quality of water quality.

Protection devices require oil-fired boiler and furnace operators furnace operation requirements in the previous article we said fuel boiler safety issues, is on this basis that we talked about the boiler room safety requirements, other than that it accident there and boiler protection requirements boiler operator requirements in order to build a secure environment. Oil-fired boiler protection device to claim 1, the steam boiler applied in varies industries must have high reliability, low-low water level alarm and interlock protection, interlock and overpressure protection. 2, the hot water boiler must be over-temperature alarm device. 3, when the fuel pressure is below or above a predetermined range of values ​​can be automatically cut off the fuel supply. 4, when the blower off, shall be automatically cut off the fuel supply. 5, to be fitted reliable ignition and flame protection program control means. Oil-fired boiler operators claim 1, after the boiler operator training posts must, must hold pressure boiler fireman operating permit issued by the technical supervision departments to posts. 2, the operator must strictly comply with the system, they are not allowed to leave their posts during the shift. 3, forbidden to store inflammable and explosive materials near the equipment. 4, abnormal and deflagration burner ignition, should stop to check. After starting the burner, suddenly turn off, start again need to wait at least 20 seconds. Flameout operation must be shut down to find reasons not boot within 60 seconds. 5, the boiler room to keep clean, good ventilation, keep dry. 6, when the boiler is disabled, you must cut off the power and close the oil valve. These are the important requirement for us to build our oil-fired boiler safety environment we want to help.

Non-staff are not allowed to switch the various valves in the boiler room, the smoke damper and electrical switches, undocumented fireman, water quality laboratory personnel are not allowed to operate separately.

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.

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.
