4000Kgs City Coal Fired Steam Boiler
Why horizontal gas 4000kgs city coal fired steam boiler to run under negative pressure? Horizontal Gas-fired steam boilers are generally negative pressure operation, if the pressure is running high temperature flue gas will cause the furnace to burn jet furnace walls and insulation, but also endanger the safety of operating personnel , the negative pressure is not too large, generally -10 ~ -30Pa, small oil-fired boiler is generally because there is no draft fan for the combustion positive pressure. For improving the thermal efficiency of the boiler has the following methods: a low pressure industrial boiler manufacturers has been designed in consideration of the problem of overheating efficiency, device, or change from the flue gas energy aspects is not possible and thus the best energy boiler operation starting from the (here not On the recovered water of vapor condensation). According to statistics survey, the current design of the thermal efficiency of domestic low-voltage industrial boilers is generally 70 to 90%, generally the actual operation of the thermal efficiency of about 60 to 80%, some even below 50%, a small low pressure industrial boilers as long as the operation, maintenance properly, design can achieve the thermal efficiency of the boiler manufacturers. I think the management and operation of the boiler should pay attention to the following points: First, to monitor the boiler exhaust gas temperature. Usually the largest boiler flue gas heat loss is a loss, so control the boiler flue gas temperature is very important, general industrial boilers low pressure gas (mainly refers to less than 10 tons of boiler and pressure of 1.6MPa, the same below) of the exhaust gas temperature is 150 ~ 180 ℃, oil-fired boiler exhaust gas temperature is 210 ~ 240 ℃, when the exhaust gas temperature is too high to find the cause and timely elimination. Causes of high temperature exhaust gas boiler are: a chamber negative pressure is too high, short-circuiting flue gases, the heat pipe 3 soot is too thick, too thick scale pan 4, etc., oil-fired boiler exhaust gas temperature is too high reasons : 1 air not adjusted oil, the oil is not completely burned in the chimney secondary combustion occurs aft, 2 soot too, the need for timely cleaning, the flue gas short circuit 3, 4 is too thick scale, etc. second, the control of boiler blowdown rate. General industrial boiler blowdown rate controlled at 5 to 10%, in the pot of water to ensure that qualified (mainly total alkalinity and pH) under the premise of boiler blowdown rate as low as possible, the sewage to adhere to the "ground row, row less, uniform discharge "principle. Third, the maintenance of good boiler furnace wall insulation. Boiler heat loss is also a relatively large heat losses, now the boiler manufacturers in the manufacturing and design has been well thought out, so we do not need to change, we just trying to be difficult to maintain. Outsourcing surface temperature generally does not exceed the boiler 50 ℃, such as too high will have to find out the reasons, timely elimination. Boiler insulation should always be kept dry for gas boilers, pressure must not run long, or easy to damage the coal furnace wall and gate and so on. Fourth, adjust the ratio of fuel and air volume, complete combustion of the fuel as possible. Small boilers generally do not have the amount of wind testing instruments, we can only go by experience adjustment. For oil-fired boiler, the normal combustion flame was yellow-white, non-glare, flame stability, no visible smoke chimney; for gas boiler, the normal combustion flame as a light yellow, no visible smoke stack, substantially cinder burn coal particles as uniform as possible. Fifth, there must be complete boiler water treatment. Complete boiler water treatment and water quality testing can maximize prevent boiler scaling and correct guidance of the sewage, but it did not do a lot of small boilers, companies usually do not pay attention.
