Plc Control Gas Steam Boiler

Plc Control Gas Steam Boiler

Gas plc control steam boiler how gas consumption is calculated: gas consumption gas steam boiler how to calculate: there are a lot of users do not know how to calculate the gas consumption of gas steam boiler steam boiler gas before you buy, there are a lot of phone users consulted, this this problem has plagued some users, it decided to write it again this morning article on "how gas consumption gas steam boiler computing", following on from me explain to you about the principles of operation of the gas boiler gas consumption formulas and gas boiler. 1. First, we first look at the gas steam boiler operating principle: the pressure of the fuel through the gas line is controlled by the flow valve through the ignition burner Automatic combustion air, the heat emitted by the heating surface of the boiler sufficiently absorbed (three return) flue gas (carbon dioxide and water) into the atmosphere through the chimney. 2. Gas-fired steam boiler fuel consumption cost analysis (we have a 4-ton gas-fired boiler, for example) fuel light oil and gas projects Rated evaporation 4t / h2t / h thermal efficiency of 92% to 92% fuel heating value 8500Kal boiler / Nm310300Kal / Kg fuel consumption amount 300Nm3 / h24Kg / h auxiliary mechanical and electrical consumption 11KW · H11KW · H fuel Price yuan / Nm3 yuan / Kg fuel costs per hour yuan per hour RMB auxiliary mechanical and electrical consumption costs the first year cost of fuel (million, according to 350 days / annualized) in the auxiliary equipment costs (million yuan, according to 350 days / year basis) of the total cost (million, according to 350 days / year basis) (Note: at 12 hours per day)

Boiler efficiency calculation formula

Definition of Boiler Efficiency is “The percentage of the total absorption heating value of outlet steam in the total supply heating value.” In other word, it is a rate how the boiler runs efficiently. The thermal efficiency of our coal-fired boilers is 84~92%, the efficiency of fuel and gas boilers is 96~99%, and the efficiency of biomass boilers is 86-93%. The higher the efficiency of the boiler, the better the heat transfer performance. Increasing boiler thermal efficiency can reduce boiler fuel consumption and reduce boiler operating costs. Increasing the thermal efficiency of the boiler is to increase the effective use of heat and reduce the heat loss of the boiler. The key point is to reduce the heat loss of the boiler exhaust gas and the loss of mechanical incomplete combustion.

Steam boiler automatically displays the instrument will encounter in the use of water which asked plc control steam boilers by fuel can be divided into electric steam boiler, steam boiler fuel, gas steam boilers. According to the structure can be divided into vertical steam boilers, horizontal steam boiler, steam boiler small single, double back to the vertical structure, large steam boiler mostly as three-pass horizontal structure. When the water level is low or groundwater automatically display meter, installed in the steam boiler only a low level means, even water too thin; when the groundwater level automatic means or instruments show lower, the steam boiler is mounted in a water only means; e no other ground water drainage means drainage cock; drum means on a level effective means further water damage; plug door apparatus can not twist the water level; a level plug door apparatus leakage leakage; means water false water level display; water level on the two drum devices are inconsistent; water glass breakage frequently means; glass protection device is not level; water means water level glass plate red indicator is not displayed; glass plate It does not show red; red glass panel is not displayed. If the apparatus dirty water, the water level can not be clearly observed. Steam boiler water level gauge inconsistencies mainly glass and clear observation of steam boiler water level gauge is not cleaned for a long time during operation, routine maintenance is not performed, resulting in water means cocks rust, soda connecting tube blockage. Or filler inadequate or aging. In addition to steam, water or tap is blocked, the phenomenon of false water level may also be due to misalignment between the steam pipes and caused the water level instrument; steam, dislocation faucet handle position will result cocks closed, but may also be due to boiler poor water quality, and water vapor and water and the water level caused by false. Broken glass is mainly water vapor, the centerline of the tap out of alignment, the bending stress in the glass tube memory, no glass expansion gap length is too large, the water level window directly blown cold, poor quality glass. During the boiler operation, we found that the water level is unclear, when the ultra-high water level should be stopped immediately, should discover the problem.

Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water boiler is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas hot water boiler. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).
