The reason why the ignition rod of gas-fired boiler has sparks but does not ignite: 1, the ventilation clearance of cyclone disk is blocked by carbon deposition, and the ventilation is not good. 2, oil nozzles are unclean, clogged or worn out. 3, the valve setting angle is too small. 4. Inappropriate distance from the tip of the ignition rod to the leading edge of the oil nozzle (too prominent or indented) 5, the first oil gun solenoid valve is blocked by debris (small oil gun). 6, the oil is too viscous to flow or the filtration system is blocked or the oil valve is not opened, so that the oil pump suction is insufficient and the oil pressure is low. 7. The oil pump's own filter screen is blocked. 8, the oil contains more water (boiling noise in the heater).

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, boiler 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.

The steam boiler can be equipped with laundry equipment to clean clothes and dry quickly. Hot water boilers are mostly used to supply hot water and heating. The atmospheric pressure hot water boiler for sale equipment delivers hot water through the hot water pipe network to the showers and sinks in each room of the hotel, providing 24-hour hot water service for the passengers.

Why should the boiler blowdown? Boiler Blowdown purposes: (1) exclude excess alkali and salt boiler water, boiler water so that the indicators, always controlled within the national standard requirements. (2) within the junction to exclude dirt green boiler. (3) oil and foam surface water boiler blowdown. Boiler Blowdown meaning: an important part of the work when sewage water treatment (1) boilers, boiler concentration is an important means to achieve water quality standards assurance. (2) the implementation of planned and scientifically sewage, to ensure good water quality boiler is slow or prevent scale knot students to ensure the quality of the steam boiler and an important measure to prevent metal corrosion.
