Natural gas competes very evenly with coal, and is perhaps slightly less expensive presently.This is changing, however, as environmental polices are being drafted that tax facilities burning natural gas in an effort to drive them to convert to non-fossil fuels. Boiler manufacturers can do little to combat this issue except redesign their how should boiler exhaust discharges to co-fire alternative fuels along with natural gas, adding the appropriate pollution-control devices as necessary.
To comprehensively promote the prevention of air pollution control work, steadily enhance the quality of atmospheric environment, located in the northern part of Heilongjiang Province held a mobilization meeting Sunwu out of small coal-fired how should boiler exhaust discharges to May 7.
Conference announced the "2019 Sunwu urban area out of 10 tons of steam per hour and coal-fired boiler embodiment."
To promote the elimination of built-up area of small coal-fired boiler work, the relevant departments should strictly follow the higher level requirements, the investigation to find out the use of coal-fired boilers and urban planning area of built-up areas, with their own reality, do a good job to implement; should attach great importance to raise awareness, according to the embodiment and objectives, and take various measures to actively promote the complete phase-out of coal-fired boilers small task; to actively publicize the relevant policies, regulations and requirements to the boiler owners, guided by the responsibility to implement, clear time node . To seek truth from facts, objective science, policy guidance, strict enforcement of the principle, in order to reduce air pollution, improve air quality and protect people's health as the goal, according to the classification regulation, departmental interaction, Duocuobingju, the overall advancement of the process steps to form a government command , business differentiation, market-driven, effective supervision, public participation in new air pollution control mechanisms, to promote the phase-out of coal-fired boilers built-up urban area.
With the implementation of the new environmental protection law and the introduction of new standards for the control of atmospheric pollution of boilers, the transformation of coal-fired boilers in various localities has been carried out in an orderly manner, and coal-fired boilers can be transformed into natural gas boilers in the actual operation. Can also be transformed into biomass boilers, but no matter how to reform, in addition to the choice of high-quality coal-fired boiler transformation company, but also need to pay special attention to the following matters.
1. When the boiler is dismantled, attention should be paid to shutting down the blower and stopping operation when the boiler is dismantled, and when the furnace temperature drops to an appropriate temperature, the boiler needs to be dismantled by the relevant parts of the existing boiler to be retrofitted to the coal-fired boiler. Stop the boiler induced fan, chain grate, then the workers enter the furnace from the fire door, remove the original furnace arch of the boiler, clean up the furnace interior, and then remove the main engine and auxiliary machinery of the boiler.
2. Attention to furnace reform is one of the key points in coal-fired boiler reform. The combustion conditions of existing boilers can be improved by reasonable transformation, which can not only accord with the combustion conditions of new fuels, but also play a better role in saving energy. However, it involves re-pouring the furnace, so special attention should be paid to keep the back arch pipe of the boiler away from the center of the flame, so that it will not be burned by the high temperature.
3. Attention should be paid to the modified boiler after a series of projects, such as retrofit of coal-fired boiler, pouring of new boiler front arch and back arch, etc., should be paid attention to after the retrofit of coal-fired boiler is carried out. One of the most important tests is to test the boiler body under certain pressure, and the boiler can be put into use only after the boiler has passed the test and revamped. These are a few things to pay attention to when reforming coal-fired boilers.
Do no install shutoff valve between boiler and safety relief valve. Install discharge piping from safety relief valve. Use 3/4 or larger pipe. Use pipe suitable for temperatures of 375°F (191°C) or greater. Individual boiler discharge piping shall be independent of other discharge piping.Get A Quote
