How to reduce the amount of fuel hot water boiler? Currently, during boiler operation, the unnecessary loss of fuel is a more serious problem, then how do to reduce the amount of fuel to some extent it? (1) water quality problems, boiler feed water at the time of selection, try to water softening, water and avoid non-compliance, resulting in late boiler fouling and other phenomenon, attached to the inner wall, affect the thermal efficiency of the boiler, increasing fuel consumption. (2) to timely maintenance of the boiler, to avoid the smoke box and other parts of dust clogging problems, resulting in unnecessary consumption of fuel. (3) To regularly boiler dust removal equipment for testing, so it appears debris clogging. (4) under the premise of the normal operation of equipment, to the appropriate use of certain energy-saving technologies, on the one hand full use of energy, while avoiding unnecessary waste of fuel. In short, the process used in boilers, fuel costs expenditure in total expenditure also occupies a relatively heavy proportion, thus ensuring reasonable measures to reduce fuel usage basis for safe and stable operation of the boiler is more necessary, in its after comprehensive consideration, to enhance the effectiveness of production per unit time of the boiler is also very effective.

CFB Boiler Combustion Efficienc

Combustion efficiency measures how effectively a CFB boiler transfers the chemical energy stored in fuel into usable heat. Reaching optimum combustion efficiency typically requires pumping additional air into the combustion chamber so that all fuel can be burned.

Recently, the Changsha City issued a notice on the transformation of low nitrogen gas boiler related documents. Details are as follows:

1, a total transformation time for two years, 2019-2020 years.

2, the transformation range: High-tech Zone, Furong District, Tianxin, Kaifu District, Yuhua District, Yuelu District administrative region, the city of hope Gaotangling Subdistrict high Tong Ling Area, Osan streets Yujia slope Area, Lake Daze in the region ban on burning streets, white sandbar streets, moon Island street, Jinshan bridge street, Golden Park street, Xingsha streets of Changsha County, Hunan Long street, Quantang streets, Langli streets, long queue streets, such as the scope of the existing town of Sha It is not less than 1 ton of steam (greater than or equal to the rated power or hot water boiler, organic heat carrier in the boiler 0.7MW) gas boiler (facility) (boiler equipment including special directory outside the range) low nitrogen unit owners embodiments transformation. Or more areas outside the area of ​​self-implementation.

3, the transformation of the standard limits: the new replacement and overall gas boiler Changsha NOx emission is less than 30mg / Nm³; gas boiler (facility) was transformed with the nitrogen oxides emission concentration of less than 50mg / m³.

4, 2019 Task: In addition to the Furong District, Yuhua District, within a range of high-pollution fuel combustion zone ban other jurisdictions to start the transformation from June 2019, 50% complete gas-fired boiler (facilities) low nitrogen transformation and complete acceptance.

5, 2020 Tasks: Before the end of October 2020 to complete all gas boilers (facilities) within the range of high-pollution fuel combustion zone ban on low-nitrogen transformation and complete acceptance.

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.
