To conscientiously implement the CPC Central Committee and State Council "on the overall strengthening of environmental protection and resolutely fight pollution prevention advice tough fight" and "the State Council on the issuance of three-year winning the Battle of the blue sky plan of action," the spirit, water tube boiler supplier in europe emissions control, prevention and treatment air pollution, the State environmental Protection Department to develop "boiler air pollutant emission standards." In order to further the implementation of air pollution control operations, all regions at the same time meet the national standard, but also have introduced a more stringent local standards.
From the implementation of the Beijing gas nitrogen oxide emission standards for boilers began 30mg, emissions from gas-fired boiler has been of great concern, expand around the "coal to gas" action, so that gas such devices become the most countries to promote clean energy boiler.
The transformation of the current common low nitrogen boiler, there are three main measures: (1) replacement of boilers, (2) replace the burner (3) in the boiler flue gas treatment.
Controlling the nitrogen oxide generated from the source, the most advanced technology on the market today is the use of flue gas recirculation techniques and FGR premix combustion gas boiler technology, both having different focus, low nitrogen emissions boiler.
Replace the boiler burner, renovation and debugging, and the impact on the safety performance of the resulting boiler, burner unit by the responsible manufacturer or his authorized. Beijing Bureau of Quality and Technical Supervision, Beijing Municipal Environmental Protection Bureau issued the "Notice on the transformation of the low - NOx combustion safety risk warning" states: the transformation of low-nitrogen combustion boiler diverse, complex technology, to protect the smooth implementation of the work of reform, effective prevent security risks, prevent accidents, analysis and appraisal by experts, it is not recommended comprehensive safety, environmental factors, the following recommendations:
Nitrogen oxides have been generated by some means and then reduced to nitrogen, the main fuel reburning, selective catalytic reduction, selective non-catalytic reduction. But in the actual monitoring, the nitrogen oxide emissions controllability is poor.
The transformation of low nitrogen gas boiler is a need for long-term adherence and actively manage the work, under the premise to meet the national standards, do specifically address the specific circumstances, not blindly, careless handling, to adopt plans, goals, ideas implementation, to achieve a comprehensive upgrade gas boiler.
1, for manufacturing defects in the design should take the following measures: First, the rational design; Second, strict material off; the third is the correct preparation of the manufacturing process instructions and process card (including repairs); Fourth, establish the necessary rules and regulations; Fifth, improve the quality and sense of responsibility operators and managers.
2, to prevent overpressure. To ensure the sensitivity and reliability of the safety valve, an automatic drain needs to be done on a regular basis. Identify problems in time, also installed on a standard gauge for comparison.
3, to prevent overheating. Effective water treatment device must be configured and set up strict rules and regulations, the boiler does not reach less furring furring, no accumulation of grease. To check the fouling situation boiler outage, if the scale must be promptly cleaned.
4, to prevent internal corrosion. For large-capacity hot water boiler, the thermal oxygen or a chemical method of oxygen. In addition, to check the situation of internal and external corrosion. The extent of corrosion such as pile up or carry out repairs Patching means in accordance with (Chief Engineer units must have the approval of the program and report to the local technical supervision departments boiler).
Steam water tube boiler supplier in europe furnace to add no water how should we do? Faced with this situation first of all to understand the local water hardness is not too high, there are a lot of local water hardness is too large volume guitar scale, resulting in a steam boiler pipes get clogged, serious pipe may burst, if steam boiler because the scale is too soon multi-generated scale will affect the boiler heating surface, steam will be sandwiched plenty of water. Supporting user said he had softened water equipment, steam boilers and no scale. The check valve should be out of the question, then opened it is true that things are stuck check valve, after removing the drenching with water after the addition of water can be normal. After a friend In such case, the election is not to see too much because of the scale of the pipeline Duzhe perspectives, but also look at the card check is not something to be with, and I hope this can help to experience this content-related friend issues.
At the same time, there is the equipment problem of water tube boiler supplier in europe water treatment. If the effluent quality of boiler water treatment equipment is not good and the effluent efficiency is not high, the scaling and corrosion of boiler will be accelerated. The main reason is that the resin is destroyed and oxidized by improper use of the resin, or the inner wall of the iron boiler is not timely, and proper treatment leads to iron poisoning of the resin.
