Low Price Condensing Gas Boiler

Low Price Condensing Gas Boiler

Startup low price condensing boiler steam temperature does not mention how high do? A: In the unit to start the process, often encounter steam pressure has reached the requirements, and the steam temperature was too much difference, especially in front of the turbine and the blast furnace or red switch occurs. Should take the following measures: appropriate to increase the amount of coal to improve the furnace heat load; adjust the secondary air ratio, increase the amount of lower secondary air; improve wind, air pressure, increased gas velocity; hydrophobic and full of air and exhaust mother pipe in front of the main steam isolation all hydrophobic.

In recent years, China's environmental protection departments have been promoting the low price condensing boiler "coal to gas" to reduce emissions, and win the Battle of the sky ", to coincide with the recent natural gas price, have not you transform coal-fired boiler, still What hesitate?

A bunch of roots of the impact of vertical steam low price condensing boiler efficiency: basically all over the country are conducting high-profile coal to natural gas movement, vertical steam boiler use, very large cuts infected micro particles, the same time nitrogen oxides and other toxic gases the smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler.

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, low price condensing 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.
