wood fired 500kg steam generator for home use

For boiler with generators, the maximum continuous flow rate of the boiler is at least 1.03 times or 1.05 times or greater than the normal continuous flow rate of the steam turbine.

On January regular press conference, Secretary, Ministry of Environment environment atmosphere Liu Bingjiang said: Through the joint efforts of the whole society, national ambient air quality is generally improving. But issues of current emissions of air pollutants is still high, industry structure, energy structure is still prominent, air pollution control remains to be done.

2019 is to win the battle of the blue sky in tackling it. China Environmental Science Research Institute Professor Xue Zhigang said China is still partial to change the energy mix of coal to Beijing and Tianjin, for example, though not local, but coal consumption per unit area of ​​5 to 6 times the national, so to adhere to focus total coal consumption areas under control.

First, the structure of coal-based energy, coal pollution characteristics significantly. Shaanxi, Shanxi coal-producing province is also the province's coal consumption, coal consumption Fenwei plain more focused, coal accounted for nearly 90% of energy consumption, much higher than the national average of 60%.

Second, the emphasis on regional industrial structure, industrial pollution emissions from large. Fenwei plain alumina, coke, iron and steel, coal, chemical and other heavy chemical industry, small-scale enterprises, low level of equipment, and most enterprises have yet to achieve a stable discharge standards, ultra-low emission completion percentage less than the transformation of thermal power enterprises in Beijing, Tianjin the level of pollution control needs to be improved.

Third, the prominent road transport pollution, emissions from large heavy vehicles. Fenwei plain is an important channel Shaanxi, Inner Mongolia and Shanxi coal Sinotrans, common to road transport, heavy industry-oriented industrial structure to further increase the pressure of road transport.

Hebei Province in 2019 government work report, determined to win the battle of the blue sky, ultra-low emissions to accelerate the transformation of key industries and promote clean coal casual alternative, "scattered dirt" dynamic business continuity cleared, Hebei Province, the year will be 10 million tons of coal Yajian thermal power 500,000 kilowatts.

Tianjin in 2019 to promote low-nitrogen transformation and construction work clean diesel transformation of mechanical gas-fired boilers, in an orderly urban and rural residents clean alternative to coal for heating, PM2.5年均浓度持续下降. In addition, Guizhou, Gansu, Heilongjiang and other places have made the coal control target.

It is reported that, after the heating season this year, the Ministry of Environment will work with ecological scientific and reasonable arrangements around 2019 bulk coal management plan. Regional authorities will further strengthen joint prevention and control, continue to implement the autumn and winter tackling action in key areas. In the future, China will focus on promoting the Beijing and Tianjin and the surrounding areas, as well as bulk coal governance Fenwei plains, to the 2020 heating season, the basic completion of the plains to live and bulk coal for heating in winter instead.

What is boilers is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler output of the fuel has a certain thermal energy of steam, hot water or organic heat carrier. The original meaning refers to the pot on the fire heated containers that hold water heater which places combustion of the fuel, boiler and furnace boiler consists of two parts. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. Provide hot water boiler hot water boiler is called, is mainly used for domestic, industrial production also have a small application. Boiler steam is known as steam boilers, often referred to as boiler, used for power plant, ships, locomotives, and industrial and mining enterprises.

Small gas steam boiler in the hotel building applications in daily production, how to save energy and reduce the emission of pollutants, reduce costs, increase economic benefits to the business, the real problem is getting attention, and gradually resolved. Shenyang is a hotel accommodation, offices, restaurants, stores in one large commercial buildings, construction area of ​​6 × 104m2. During the heating period, heating systems, domestic hot water steam system, laundry room used by the municipal heat supply network. After the heating period, domestic hot water systems, steam laundry prepared from 2 model white WNS8-1.25-YQ fuel steam boiler (heating of serving as backup boilers) for the steam, steam production of single 8t / h. Steam boiler room to the sub-cylinder (in the basement podium) linear distance is 200m, and specifications for the steam supply pipe DN250mm, Buried employed, the compensator 4 disposed manhole. Based on the actual measured amount of steam on the hotel, and the application of energy-saving small gas steam boiler in the hotel building were discussed. Selection 2 gas steam boiler us 2009 June 7 to July 1 for steam consumption for domestic hot water systems, laundry room were measured. Average pressure of 0.08MPa steam, hot water systems, laundry average daily amount of steam were 7.43,2.43t / d. Two systems together, the maximum amount of steam per unit time and the average amounts were 0.77,0.41t / h. From the measured data, daily 9: 30-11: 30, 15: 30-17: 00 cooking gas peak, the highest air consumption is 19.65m3 / h, the hotel into the household gas pipeline gas supply capacity of 95m3 / h. According to domestic hot water, laundry room two systems unit time summer highest steam consumption is 0.77t / h, should be used in a 1t / h gas steam boiler, its gas consumption is 76m3 / h. In actual use, reasonable arrangements for gas time, can fully meet the demand for gas gas steam boiler. From the above analysis, the steam production of the hotel is much larger than the existing fuel steam boiler steam summer practical usage. According to the measured summer daily expenditure of more than just fuel costs more than 3000 yuan / d. Underground layer may be mounted on a podium 1t / h gas steam boiler, steam lines since all indoors, and therefore low cost pipeline system, and reduce the emission of pollutants, environmental protection efficiency significantly. 3 gas steam boiler room design of the hotel podium underground over 3 floors, including the basement of the original generator set oil storage has been discontinued, construction area of ​​about 60m2, close to the basement exit ramps from the gas pipeline into the family 8m, after transformation, can be used as gas heating boiler room. Gas heating boiler heating system flow shown in Figure 1. Gas heating boiler to be mounted ventilation system, the ventilation normally not less than 6 times / h, accident ventilation of not less than 12 times / h, the amount of exhaust air volume should be slightly larger, so that the boiler room space maintain positive pressure, and the ventilation should be selected proof products. Gas heating boiler to be mounted combustible gas detection and alarm devices, combustible gas detection and alarm device to automatically signal when gas leakage occurs, the emergency shut-off valve closed and to ensure that no further leakage of the combustible gas. Water spray system shall be installed, and the sprinkler system in conjunction with the original. Gas heating boiler in order to prevent water from leaking into the premises are ground floor, the ground should boiler room waterproofing and drainage ditch, the concentrated water discharged to the ground floor drainage system pressure, into the room promptly [1,2 ].
