olive pomace fired boiler for food beverage
After the explosion of the tube, the explosion of the furnace tube will occur, analysis of the furnace tube, found that the upper part of the explosion has been blocked by scale, the blocking position is located at the bend of the furnace tube, the scale is white, through laboratory analysis, The main components were CaCO3 (69.4%), MgCO3 (12%) and Fe _ 2O _ 3 (7.5%). Because the furnace tube forms scale in the upper high temperature region and the water circulation is not smooth, under the action of high temperature, under the action of radiation and convection, the convection heat transfer inside the furnace tube is destroyed, the furnace tube overheat, and the tube burst under the action of olive pomace fired boiler for food beverage pressure. Scaling of furnace tubes, as shown in figure 3.
Sewage long time, a waste of a lot of heat, affect heating steam pressure; two pairs of olive pomace fired boiler for food beverage water circulation unfavorable, water wall tube burst will occur in severe cases.
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, olive pomace fired boiler for food beverage 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.
Now people go and see the situation itself of the business aspects of the gas olive pomace fired boiler for food beverage to take into account when such a choice is that people will be able to see from your own understanding of different aspects of the most part, this is now possible to analyze people it is obvious good advantage, so people can see the situation now is completely different approach of.
