Condensing hot water boiler room What are the requirements for electrical engineering condensing hot water boiler room electrical professional requirements: (1) condensing hot water boiler room should be set explosion-proof, waterproof lamps. It requires sufficient illuminance in the boiler water between the condensing operation. Pressure gauge readings particularly important should gauge and other specialty lighting set, to avoid operator error: (2) condensing at coal-fired hot water boiler and ancillary equipment has just started, often due to various factors which cause the motor apparatus starting current exceeds the normal range, the device can not start or cause air switch [burned). So, with the operating personnel should take measures to reduce the starting current of the motor, the normal operation of equipment. (3) In order to accommodate automation of the control of the fuel gas condensing boiler water, boiler water condensate should each equipped with the appropriate control cabinet. [Coal-fired boiler control cabinet or disk) should be provided to monitor the position of the operator within the scope of the, condensation can always observe the movement of the hot water boiler and associated equipment. (4) for conveying gas, liquefied petroleum gas fuel line (of metal tubing) should be set static grounding means when the condensing boiler house electrical system ground with lightning protection network and can be connected thereto, or should be provided static grounding system. (5) condensing the gas vent pipe for hot water boiler, which should be installed on top lightning. (6) Where the control and monitoring of the condensing boiler water level, pressure, gas leakage alarm, etc. haggard meter device shall ensure sensitivity, and to ensure the quality of agricultural instruments necessary testing and checking devices. (7) respond to electrical materials (including power, lighting, automation instrumentation systems) in construction strictly. In order to ensure safe and reliable operation, especially for gas condensing hot water boiler room, often professional electrical short circuit or other accidents can have serious consequences.

Depending on the application, energy-saving gas-fired mainly divided into the following two categories.

First, heating boilers, boiler bath

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.

Power Plant Boiler

Thermal power generation is the main way of generating power in China, power plant boiler as one of the three main equipment in power plant, developing with the development of China's thermal power industry.
