In view of the possible near-term benefits, ZG recently funded an assessment of coal fired power plants equipped with three different combustion systems: Kinds of coal, Circulating Fluidized Bed (CFB), and biomass fired circulating fluidized bed. The purpose of this study was to establish, through engineering analysis, the most cost-effective performance potential available through improvement in the steam conditions and combustion systems.
Henan district heating gas fluidized bed coal boilers 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.

The onset of winter, to ensure the safe operation of heating fluidized bed coal boilerss, recently, Fengning, Hebei Province Market Authority to schools, hospitals, residential, hotels, enterprises and other crowded places as the focus, to carry out security checks special action winter heating boiler.
The boiler safety inspection to check whether the action is mainly for the use of registration certificate, whether or not the maintenance, overhaul and maintenance, boiler safety accessories are conducted periodic inspection; the use of units to establish whether the relevant rules and regulations and safety rules, file information is complete, run record is perfect; whether the unit is equipped with the required safety management, whether fireman and water treatment personnel certificates; whether developed special equipment safety measures and emergency rescue plan, with related emergency rescue equipment.
Through this inspection, supervision and special equipment unit firmly establish the safety production of "red line consciousness" to strengthen the routine inspection of the unit and boiler maintenance work in a timely manner to eliminate potential accidents.
