In search of higher efficiency and lower emissions, much of the new interest in coal has been directed toward second generation technologies such as coal gasification combined cycle and fuel cell systems that utilize hydrogen derived from coal gasification processes or natural gas fuel. There has also been research exploring other advanced power plant systems that generate chemical products in addition to generating power.
Henan district heating gas excellent quality coal fired boiler heating characteristics and uses of a cell or several cells share one building gas boiler room heating using the secondary heating network, an intermediate heat transfer station, the larger the size of the external heating network. Heating area up to several million square meters of high-altitude emissions fumes. 1, Henan area gas boiler heating system to the Characteristics of A, using the advantages: gas boiler Henan province invested more decentralized heating, can achieve centralized management, easy maintenance and users can achieve high-altitude emissions of pollutants. Coal to gas project, you can use direct existing heating systems and boiler room ancillary equipment, saving the initial investment. B, there is a drawback: the thermal efficiency is relatively low, and heat transfer stations outside the network heat losses and the heat medium conveyance power consumption, high emissions of pollutants, the system adjustment is not flexible, large investment outside the network, does not solve the problem of direct measurement of the heat. In the beginning of the construction of the system utilization is low. The end of central heating systems without measurement and adjustment means. Flat Rate according to heating area. Hydraulic imbalance caused by high temperature heating part of the user, when the room is overheated, the user typically using cooling method fenestration adjust the room temperature, resulting in 8% to 15% of the heat loss. Particularly in the construction of mixed use of different nature, according to the same level of heating, because no means of regulation, office buildings, schools and other heating at night and holidays, the hotel was no usual heating, waste of energy. 2, Henan gas boiler gas consumption due to heat loss outside the network is greater than the dispersion of Henan gas boiler heating, the heating temperature is higher than the average gas boiler single-family household heating Henan, Beijing heating in the gas consumption index 10-14m3 / m2. Gas consumption is mainly due to heat loss and heat transfer stations outside the network than other reasons for the high two ways, hydraulic imbalance serious nature of the use of different architectural mix caused by heating. 3, the heating system uses the ground region Henan gas boiler pollutant concentration requirements more stringent, while heating the dispersion concentration of pollutants discharged warm floor exceeded, central heating may be employed. However, there are requirements for stack height shall be determined through calculation. Rarely used in Europe and North America gas central heating boiler area, or are generally thermoelectric cooling and power generation.
President of the association leaders to introduce this year is an important period of the 20th anniversary of the group. After 20 years of development, the Group to "create convenient excellent quality coal fired boiler boutique users" for the mission, adhere to scientific and technological innovation, all-round, multi-channel strengthen technological innovation, we have launched a variety of users for the use of energy-saving, low new nitrogen, gas boiler to become the industry leader. Luhai Gang Jiao Ling Wang, president, accompanied by the Secretary-General and his party visited the Group's newly completed R & D base, clean fuel test center, exhibition hall and a multimedia remote monitoring center.
Necessity textile mill converted to a coal-fired excellent quality coal fired boiler gas boiler is a boiler equipment industry needs is more important, because a lot of links to the papermaking process requires a lot of steam drying, stereotypes and so on. However, along with the national policy of environmental protection departments to ban coal-fired boilers, and now more and more manufacturers have to use coal-fired boilers to coal-fired boilers upgrading or purchasing a new low - NOx emissions. Mills from coal to gas boilers is an important direction of the current transformation of coal-fired boilers, is one of more types of enterprise transformation, especially in the area more natural gas, coal into gas boiler is the main way. 1, in order to transform mechanization layered fired boiler gas boiler, you should first remove the front arch and a rear arch, while increasing the bottom heating surface, instead grate, grate to prevent overheating, combustion; 2, through the furnace heat transfer calculation methods determining the size of the boiler, furnace flame center position, and then pouring furnace work. In order to avoid the center position after arch boiler tubes, based on the original slope of the original arch made pipe. 3, the furnace in order to prevent an explosion, when the coal-fired boiler furnace gas is substituted, or when fuel not atomized combustion gases in the furnace incomplete combustion or heating surface of the end of the furnace, a fire or explosion occurs, should be mounting the appropriate parts of the boiler explosion vent, and to increase the ignition and flame failure protection program control to automatic control means, to ensure safe operation of the boiler. 4, is closely related to the selection and arrangement of the burner and furnace, the filling degree of the flame in the furnace should preferably not to form a dead air. Gas burner arrangement considered reasonable and piping layout, convenient operation, inspection and maintenance;
