Jinzhou construction and installation company needs an electric heating hot water 5 ton boiler seller house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.
Coal-fired 5 ton boiler seller economizer economizer effect to save the name suggests is a secondary member of coal fired boilers and the like for the device, the principle is to use the coal-fired boiler economizer flue gas heat exchanger for heating the feedwater. Economizer heat absorbing smoke, reduced exhaust gas temperature, by improving the thermal efficiency of coal-fired boilers, to achieve the purpose of saving coal. Secondly, in the coal-fired boiler feedwater into the drum, since the exhaust gas after the preheating heater temperature increased, reducing the temperature difference between upper and lower walls of the drum, the drum reduces the thermal stress of the upper and lower walls coal-fired boilers, to reduce the vertical drum wall temperature difference due to damage, protect the safe operation of coal-fired boilers, coal-fired boilers to extend the life of the road.
Steam 5 ton boiler seller pressure gauge should pay attention to matters 1, rated steam pressure less than 2.45MPa steam boiler and pressure gauge accuracy not only in 2.5; rated pressure steam boiler child or equal to 2.45MPa, the pressure is too spread made not less than 1.5 level. Dial gauge diameter of not less than 100mm, in order to ensure the operation of the operator to see the surface of the pressure value shown. 2, should draw the red line on the dial gauge steam boiler, he pointed out that the maximum allowable working pressure. 3, the steam boiler pressure gauge should be provided at a convenient place to observe and purging, and to prevent the high temperature affected, freezing and vibration. 4, steam boiler pressure gauge should check at least every six months once the check should seal. 5, the pressure gauge connection tube steam boiler should leaks steam leakage phenomenon, otherwise it will reduce the pressure instruction value. 6, a steam boiler gauge scale element should be compatible with the measured working pressure, working pressure, typically 1.5; 3 times, preferably 2 times. When no steam boiler gauges, pressure gauges or pressure damage did not meet the requirements of the apparatus, boiler steam pressure gauges of the following circumstances, should stop using: 1, the surface glass breaking or blurred dial scale; 2, no seals , damage or seal verification period exceeded; 3, no pressure gauge pointer finite bit staple staple can not be restored to the limit at infinite set of bits from zero gauge pressure exceeds the pressure data bits garment allowable difference?; 4, the jump table or a pointer leak; 5, other effects gauge accurate defect. The use of the accumulator: the accumulator for a hydraulic accumulator system intermittent mechanical, hydraulic fluid may be stored in the actuator output when a batch or a low speed, and the actuator requires a large flow of fast-moving, as an auxiliary energy providing oil to the system together with the hydraulic pump, oil pump and thereby achieve miniaturization of the entire hydraulic system, to achieve the object of absorbing the impact energy sudden change fast opening and closing valve and the hydraulic load, the system generates a pressure shock, pet cause vibrations and noise, and even damage the machine. The accumulator can be alleviated, which absorb fluid shock absorber pressure pulsation absorbing accumulator, and reducing the pressure pulsation and flow pulsations of various pump, thereby reducing system noise and vibration. Having a damping effect of the gas spring accumulator, it can be used to absorb the mechanical vibrations between the body and the traveling wheel of the vehicle and the like. The accumulator can be balanced upright actuator (hydraulic cylinder) and gravity load decreases when the potential absorption into hydraulic energy store, while generating the rate-limiting resistance; upright when the actuator rises, releasing the original absorbing energy accumulator , together with the pump oil to the hydraulic cylinder, in order to achieve balance and energy.
6 tons adjusting a combustion gas steam 5 ton boiler seller, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.Free Chat
