high efficiency natural gas fired hot water boiler

high efficiency natural gas fired hot water boiler

Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.

Measures to increase the gas steam boiler economy which economy improving gas steam boiler can not only reduce operating costs, but also in line with the national energy saving policy requirements. Specifically refer to the following measures: 1, to improve equipment management level, efforts to reduce internal and external leakage thermal equipment and systems, reducing the working fluid and heat loss. 2, improve the economy auxiliary operation, to reduce the loss of auxiliary equipment, making it possible to run in the high zone. By testing to determine its associated auxiliary systems of reasonable conditions in the different operating modes of operation, efforts to reduce power consumption rate. 3, chemical strict supervision of the boiler operation, strict control of condensate water hardness, the amount of dissolved oxygen in the feedwater, boiler feed water and the PH value of water, steam quality, to prevent the boiler heating surface, condenser, heater, and corrosion of turbine flow section, fouling and salt accumulation caused by the deterioration of boiler equipment operating conditions. 5, to take measures to save water and power, such as to maintain a reasonable rate of circulating water is concentrated, and to improve the ratio of gray water recycling waste ash comprehensive utilization. 6, the main measures of force cycle efficiency is the main steam pressure, main steam temperature, reheat steam temperature is maintained at a predetermined value, back to normal investment in thermal efficiency, water temperature in the design value, efforts to reduce back pressure steam turbine and so on. 7, to improve the efficiency of the steam boiler, a steam boiler to reduce the exhaust gas temperature, air leakage rate boiler fly ash combustible content, good milling system to adjust combustion boiler test, develop various conditions of operation of the card, as the operator operating personnel in accordance with. Yaoan gauge 8, to strengthen the fuel management, strict measurement, strict control of coal into the plant, allowing coal from the design value is within the limit value, especially for volatile coal, ash, sulfur, strict supervision coking characteristics the boiler can run under good conditions. 9, strengthen metrology run, the boiler operation indicators to quantitative analysis, provide a reliable basis for the economic operation of the steam boiler. Zheng gas steam boiler pot consists of three parts: main boiler, chimney and piping system, wherein the host section has been completed and the chimney is manufactured in the factory, the host supporting the pipes and valves, the meter has been properly installed randomly transported to the host site and can be assembled chimney. Field gas supply is turned on, power supply, water line to test. Greatly reducing the installation cycle, and can ensure product quality.

Fire boiler design pitch is much: a room, boiler production plant belongs to class D, to a steam boiler rated evaporation 4t / h, when the rated output is greater than 2.8MW high efficiency fired hot water boiler, the boiler room building fire resistance rating of not less than two ; rated evaporation steam boiler is less than or equal to 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; m-inter-tank, oil pump and the oil heater are inter production plant belonging to class C, not less than two of its construction fire rating, between said room is arranged within the auxiliary boiler room, a room should be set apart from other firewall; March and gas regulator production plant belonging to Group A, which building fire rating of not less than two, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors should open outwards and should not directly access to the boiler room, the ground should not be spark Ping.

How to make boilers more energy-efficient? (Common measures) 1. boiler design of energy-saving measures (1) boiler design, first of all should be a reasonable selection of equipment. In order to ensure safety and energy conservation in the industrial boilers meet user requirements, should be due to self-select the appropriate boiler design boiler type in accordance with scientific and rational selection principles. (2) when the boiler selection, but also the right choice should be based on the type of boiler fuel boiler, industry, geographical install a reasonable choice of fuel type. Reasonable blending the coal moisture, ash, volatile matter, particle size and other combustion equipment meet the requirements of the importing boiler. At the same time, we encourage the use of new energy sources such as straw briquettes as an alternative fuel or blended fuels. (3) In selecting fans and pumps, to select a new type of energy-efficient products, can not choose backward out of the product; boiler operating conditions by matching pumps, fans and motors, to avoid the phenomenon of the "big horse car", the current inefficient use, a large auxiliary energy consumption, should be modified or replaced with energy-efficient products. (4) a reasonable choice of parameters boilers generally at efficiency of 80% to 90% of the maximum rated load, as the load decreased, the efficiency also decreased. Capacity boilers generally used with greater than 10% of the actual vapor on the line, such as when the selected parameters are not exactly according to the standard series, the boiler can choose a higher gear parameters. Auxiliary boiler selection also refer to the above principles, to avoid the "big horse cart." (5) reasonably determine the number of boiler principle is to be considered normal boiler maintenance shutdown, and pay attention to the number of boiler boiler room, no more than 3 to 4 units. (6) a boiler economizer SCIENCES designed to reduce heat losses and improve the thermal efficiency of the boiler, economizer heating surface disposed in the boiler backpass, boiler feed water is heated by heat of the flue gas, to save energy, the installation Xingmei after, a feedwater temperature increase the temperature difference between the boiler water and feed water is reduced, reducing the thermal efficiency of the boiler feed water is generated. Countries: where <4 t / boiler flue gas temperature is not greater than 250 ℃; ≥4 tons / boiler flue gas temperature is not greater than 200 ℃; ≥10 tons / boiler exhaust gas temperature is not greater than 160 ℃, province or should be installed coal is.
