dzl chain grate steam boiler with solid fuel

Recently, the Tianjin Beichen District issued a "Tianjin Beichen District in 2019 to win the Battle of Blue Sky battle plan" (hereinafter referred to as "Plan"). "Plan" put forward: to strictly control new coal projects, the implementation of coal consumption reduction project alternative, prohibit self-supporting construction of coal-fired power plants. Complete the transformation of low nitrogen gas-fired boiler more than four before the end of September 2019.

Details are as follows.

1, reducing the total coal consumption in 2019, the region's total coal consumption and coal in primary energy requirements meet the relevant indicators. Strict control of new coal projects, the implementation of coal consumption reduction project alternative, prohibit self-supporting construction of coal-fired power plants.

2, ongoing heating, agricultural, industrial and commercial management of coal-fired boilers, coal-fired boilers to burn consolidate shut down rectification results to ensure that no rebound. Carry out special rectification coal, coal supervision prominence to the implementation of high-quality coal supply and security, supervision and management of coal enterprises to establish a purchase and sale accounting, prohibit the sale of low-quality coal does not meet the requirements of state and city, by increasing the sampling frequency, strengthen information disclosure, strict qualification management, according to the law firm did not check other means, to crack down on low-quality coal to maintain circulation, sale and use of high-pressure situation. Ongoing heating season heating companies burning coal quality inspection. Strictly implement the relevant requirements of the city, set up to ensure that the region is no longer operating coal storage space, strengthen supervision.

3, to promote the safe and orderly clean warm winter residents. The completion of the outer ring 23 000 residents in rural areas "coal to electricity," the task before the end of October 2019, the region's urban and rural residents to achieve bulk coal for heating, "cleared."

4, before the end of September 2019 to complete the transformation of more than four low-nitrogen gas boiler. The full implementation of leak detection and repair (LDAR) system. Ensure the region involving volatile organic compounds emissions from industrial enterprises and supporting environmental protection facilities full coverage, stable and meet the relevant emission standards.

Gas dzl chain grate steam boiler with solid fuel operating principle: a steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporize into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source.

In the personal interest, this approach not only subtracts the cost of chemicals but also avoids the expense of water quality analysts, but it does not fundamentally solve the problem of boiler scaling and corrosion. At the same time, it not only causes the waste of energy, but also reduces the service life of boiler. Moreover, if the scale inhibitor is not used properly, it will have the opposite effect on the protection of the boiler, accelerate the scaling and corrosion of the boiler, and bring a serious threat to the normal operation of the boiler.

Notes on the transformation of low nitrogen gas burner boiler commissioning and maintenance of the boiler to avoid combustion air pollution have some time environment, so people will be ordinary boiler has been transformed low nitrogen boiler, in this way good reduce or avoid the harmful substances, but during the process of transformation should also be a degree of commissioning of the gas burner. Specifically, its commissioning and maintenance considerations include the following aspects. First, pay attention when the ignition can not be taken if handled properly when using low nitrogen boilers, gas burners found two consecutive ignition can not succeed, then this time there is an issue, after all, and should stop immediately and conduct a detailed inspection. Repair boiler manufacturers specializing in the production of low nitrogen stressed in particular the gas supply system to see if the problem burner, while the circuit to check for broken wires or the like, after the investigation and the prompt reasons, to be able to ensure that there is no problem re-start. Second, pay attention to prevent a fire or Mars due to the use of low nitrogen when the boiler to use the gas, thus making related to debugging time around can not determine whether there is leakage phenomenon and the like, and therefore must not ignite the fire or even smoke, there is Mars or is the situation as static electricity is very dangerous, likely to cause a fire or explosion, so to put an end to these phenomena. Low nitrogen boiler manufacturers emphasize not smoke or be forced to thrash metal shell are less able to welding or cutting on site, in order to avoid a major accident. Third, note that valve maintenance before failure to valve failure safety measures if a low nitrogen gas supply line and has a boiler under aerobic conditions, then before disassembly and repair should be performed first turn off the main valve to prevent gas leakage and then the main valve pilot valve section of pipe which may be present in a gas vent, and then be able to disassemble and repair. But low nitrogen boiler manufacturer reminder should be noted that even if the body has been emptied, but the pipe wall may still be residual gas or liquid gas ingredients, so making repairs when we must avoid spark or static electricity, so as to avoid any eventuality. These are the transformation to a low-carbon gas burner boiler commissioning and maintenance considerations aspects included, in addition, the process of debugging and repair in the field the tools used must have explosion-proof function. And a professional manufacturer of low nitrogen boiler must be reminded to do for the steam pressure test to check for leaks phenomenon before the burner starts can be determined only after the correct use.
