What Are Condensing Non Condensing Boiler

Gas what are condensing non condensing boilers provide both hot water and heat for people's lives, in the industry also has a significant place. But gas-fired boiler in operation, not only the boiler, also need to have a series of auxiliary equipment, work together to stabilize the operation of the boiler.

(5) Other what are condensing non condensing boiler parameters(feed water temperature, exhaust temperature )

2. Which country will the boiler be used in?

Gas hot water what are condensing non condensing boiler maintenance during the shutdown as we all know, the heating of the heating unit in our country is from October 15 to April 15, the six-month heating season the north, in industrial production, gas hot water boiler is only used winter heating. After the winter heating season, the hot water boiler will be idle. To ensure the normal operation of the hot water boiler next year, can not relax to maintain idle period. 1. When idle, the boiler water is discharged and should be placed in a ventilated place. Second, the hot water boiler furnace repair cracks need to find specialized personnel to repair, if necessary, be coated with an external lubricating furnace or anti-corrosion paint. three. Different methods and disintegration downtime 1, boiler water drained, draining suction process when the boiler is shut down three days or less, ammonia and hydrazine before shutdown, feedwater PH value to 10 or more, and then a certain pressure the drainage furnace, keep the system dry. 2, the film formation method when the amine protecting the furnace off over three days, the protective effect of the film formation is preferably an amine, such as pure octadecylamine protection, i.e., protection of octadecylamine was added a solution of pure water vapor in the system before the oven is turned off. 4. Different methods used during the non-disintegration of the stop 1 and, maintaining the gas hot water boiler pressure method: discontinued within 1Od, discontinued before increasing ammonia, hydrazine dosage of the feed water to raise the pH above 10, to maintain the boiler pressure. 2, gas protection law: if the operation is suspended for more than 10 days may be by gas protection method for long-term protection of the boiler. Fifth, the gas hot water boiler maintenance boiler off Desiccant method, the boiler water temperature dropped to 100-120 (?) All C is discharged, the water in the furnace, the metal surface of the dry heat boiler, the system scale, slag all clean, and a desiccant to keep dry the metal surface, to prevent corrosion.

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, what are condensing non 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.

Whats the Difference between a Condensing and Non

In a condensing boiler, however, the exhaust from the fuel burning process is routed to a secondary heat exchanger (a process that never happens in a non-condensing boiler), which extracts more heat and diverts it back into your heating system. By pulling more heat from the fuel burning process, and by running cooler overall, a condensing

The main reason why condensing boilers are better than non-condensing models is that they are at least 25% more efficient. Their level of efficiency is achieved by using waste heat in flue gas to preheat the cold water entering the boiler, capturing more heat from the outside rather than the inside of a room.
