Diesel 1800kg steam per hour boiler
Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast diesel 1800kg steam per hour boiler steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
Issued from the national energy conservation policy and supervision of view, the country to promote low nitrogen determination diesel 1800kg steam per hour boiler is unabated. With the improvement of people's living standards, the requirements of the living environment has become even more stringent air emissions standards for pollutants are decreasing year by year.
Burner gas diesel 1800kg steam per hour boilers were burned there a way to solve the gas boiler has been running well, but this can not be used suddenly, after checking to confirm that the burner is damaged up. What are the reasons can cause burner gas boiler is burned? For such problems, what can be the solution? Gas boiler burners burn have a relationship with a number of factors, for example, there may be a way to let the boiler temperature deviation high, has reached the upper limit of the allowable range, so that the high temperature flue gas furnace radiation heat of the burner is enhanced, the wall temperature of the burner nozzle is increased burning. It is also possible with a gas flame furnace boiler deflected about the base, because after testing found furnace temperature and burner nozzle with uneven distribution of temperature, wind speed and orifice layer with the four corners of boiler burners significantly uneven. In addition, gas burner boiler equipment standards at fault, not the end of a stable tangential firing, but also so that the other main reason for the flame base skewed. When adjusting the gas boiler, if the wind speed control of the secondary is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Further, when the adjustment is not timely gas boiler load changes the level of the upper orifice of the secondary throttle will be cooled so that the burner is not burning. After the burner for damage affecting the entire gas-fired boiler it is very large, so users in the usual course of adjustment is necessary to strengthen the control of the boiler, including the timely and quality control gas pressure changes in circumstances, gas and hot air to ensure reasonable ratio; when viewed ignition gas, adjust the size of the second damper, to change the operating angle of the operating layer when necessary; when the low load conditions change, to adjust the negative pressure combustion furnace, adjusting gas, the ratio of hot air, to ensure that the furnace coordination with the flame does not skew the layers of good gas opening. Further, the material can be appropriately improved gas burner in the boiler, it is recommended to select superior steel materials, wear resistant and adding functionality. Selection of swirler vanes refractory steel material, so to avoid burning due to swirling vanes configured fall burner opening deformation damage. In addition, be sure to strict accordance with the drawings need to adjust the gas boiler burners standards to ensure tangential firing flame in the furnace, ensure the stable operation of the gas boiler. On the practical application of gas-fired boiler There are many different applications and different habits, a variety of problems, if users also encountered other problems, you can consult our technical staff, to welcome the advice, we will the attitude of enthusiasm for your service needs.
The effect of Henan Gas diesel 1800kg steam per hour boiler feed water temperature of the boiler in order to improve the thermal efficiency of the entire plant, Henan power plant is equipped with gas boiler feedwater heater, the heater previously referred to pump low pressure heater, after giving the high-pressure pump called heater. By high pressure feedwater heaters, water temperature greatly increased. For example, medium pressure feed water temperature of the boiler mostly heated to 172 deg.] C, the high pressure furnace was heated to 215 deg.] C Usually, ultra-high pressure boiler feed water is heated to 240 deg.] C, sub-critical pressure boiler feed water is heated to 260 ℃. When the high pressure feed water heater due to the leakage of high-pressure heater water splitting in operation through the bypass to the gas boiler. Henan gas boiler feedwater temperature is lowered, the fuel portion of the heat to be used to increase the water temperature. If evaporation unchanged, will increase the amount of fuel, the furnace exit gas temperature and flue gas flow rate must be increased to increase the heat absorption of the superheater, the steam temperature is bound to increase. After Henan gas boiler feed water temperature decreases, assuming the same amount of fuel, since the portion of the heat used to increase the fuel water temperature, reduce the heat to generate steam for the evaporation of time due to the combustion conditions constant, smoke Furnace Outlet constant temperature and flue gas velocity, the superheater heat absorption is not reduced. However, due to the reduced evaporation, steam temperature inevitably increases. Therefore, water temperature decreases, the temperature of the steam will inevitably increase.
