Best selling coal fired steam SZL industrial boiler

Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, best selling coal fired steam szl industrial boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.

To enhance the thermal efficiency gas best selling coal fired steam szl industrial boilers What environmental policy: the combustion efficiency of combustion represents the degree of complete combustion. To improve the combustion efficiency of gas boilers and environmental protection, we must try to adjust the combustion conditions and better organization of the furnace, fuel combustion, reducing q3 and q4. Gas boiler environmental protection reduce exhaust gas temperature: at present China's industrial boiler flue gas temperature is high, is one of the main reasons of the low gas boiler thermal efficiency and environmental protection. Each small boiler flue gas temperature decreased 15-20 ° C, 15 ° C decreased every large boiler, a 1% increase in the thermal efficiency of the boiler gas. Accordingly, to try to reduce exhaust gas temperature flue gas heat recovery, reducing heat losses q2, the fuel savings. Softened water supply and condensate recovery: boiler feed water softening treatment and condensate recovery measures is to improve the thermal efficiency of the boiler. Raw water contains various impurities and fouling material, if not the water treatment boiler fouling. Low thermal conductivity of the scale, so that once the heating surface fouling due to increased thermal resistance, gas boiler output decreased to increase coal consumption, reducing the thermal efficiency of the boiler. Boiler keeps running at rated load: When natural gas boiler overload, due to the amount of fuel to be increased, the coal seam thickened, grate speed, air volume must be increased to meet the increased load required. Thick coal seam and grate faster incomplete combustion of the solid increase in losses due to increased air volume, the short residence time in the furnace flue gas, some burning of combustible gas has not finished on the drain with the flue gas, so incomplete combustion gas heat loss is increased. Meanwhile, when the overload operation, since the furnace temperature is increased thickening seam, exhaust gas temperature increase accordingly, so that heat loss is increased. Boiler low load operation, the amount of reducing gas, the furnace temperature is lowered, deterioration of the combustion conditions, incomplete combustion loss q3, q4 is also increased. When the boiler load is only 50%, due to a significant reduction in temperature in the furnace, it is difficult to maintain stable combustion furnace. Low load operation relatively increased heat loss, the overload or low-load operation the boiler will result in reduced thermal efficiency of the boiler. Strengthen the insulation, sealing, anti-leakage, anti-risk: Due to the wall gas boiler, soda temperature heat pipe system is better than the boiler room air temperature is high, so that part of the heat pipe system and soda furnace wall to radiation and convection to the loss of ambient air, heat radiation loss becomes the boiler. Only the furnace heat of the heat loss, reduces the temperature of the furnace at the same time, it affects the combustion. Therefore, the use of advanced insulation materials to strengthen the walls and heat insulation boiler pipes, reducing heat loss and improve the thermal efficiency of gas boilers and environmental protection. Temperature and security issues to resolve gas steam boiler

First Affiliated Hospital of Bengbu Medical College, responsible for staff to feedback to our company, this best selling coal fired steam szl industrial boiler to use less smoke production, in line with the special requirements of the hospital surroundings and national requirements for flue gas emissions. During the boiler installation and operation, square quick technical staff also always concerned about the dynamic boiler, parties can feel really real fast customer service, using fast boiler is assured. --customer feedback

The reason gas steam best selling coal fired steam szl industrial boiler flame of abnormal phenomena and processing method. Flameout for the following reasons: 1. Auxiliary trip or power interruption. 2. boiler combustion instability. 3. When the load is too low, due to the sudden drop in load, ignition energy mill will be lost or the combustion is automatically stopped. 4. mutation coal, low volatile or low calorific value. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. 5, the automatic combustion flame detectors or failure resulting in failure to trip mill. 6. The furnace wall or squib serious improper boiler soot-blowing operation, a large amount of steam into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a substantial amount of fuel reduction or interruption. A large amount of water or impurities in the fuel oil gun clogging, or atomized vapor pressure is too low. Second, the phenomenon: 1, furnace pressure was significantly higher, flameless furnace flame monitoring CRT display. Pit of fire no fire. BTG MFT alarm window alarm indicator lights. 2. The unit load is reduced, steam flow drops rapidly, and the temperature of each section of the working medium vapor pressure decrease, a sharp increase in oxygen index. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 3. Treatment: 1. If you refuse to run MFT protection, emergency stop should be handled according to the situation and stop the supply of fuel. 2.2. Identify the cause of stalling, and try to eliminate it. Conduct a comprehensive inspection of the boiler, and to confirm proper before the device is restarted.
