1 mw oil fired hot water boiler for hotel
Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, 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.
The fuel oil of the oil-fired boiler is injected into the furnace by the incinerator and shows fog-like oil droplets, which is easy to mix with the air and burn rapidly and exotherms rapidly. Compared with the coal-fired boiler with the same parameters and capacity, the thermal strength of the furnace volume can be doubled to 1046.6 × 10 kilo coke / m / m ·h. However, in order to reduce the heat load in the incinerator area and avoid the overtemperature of the water wall tube in this area, the furnace volume is only reduced by about 1 / 3. Because the ash content in fuel oil is very little, it does not form slag on the convection heating surface, so the flue gas temperature of furnace outlet can be up to 1300 ℃, and the pitch between tubes of convection heating surface can be reduced to improve the flow rate of flue gas. Then the heat transfer coefficient of the heating surface can be improved and the heating area and steel can be saved.
Hefei Limin Pharmaceutical Co., Ltd. Nanjing Military Region, formerly the backbone of pharmaceutical companies, the main drug is slowly swallow rather teabag, relying on advanced R & D platform to carry out contract manufacturing, OEM OEM and other business cooperation. China's environmental protection development trend began to take shape, many environmental policies have been put forward for a positive response to the national environmental policy, Limin Pharmaceutical decided to introduce a gas station steam boilers. After an investigation of the boiler market, Limin Pharmaceutical fast boiler is strong comprehensive strength and wealth of experience working for many years in the pharmaceutical industry to attract, party fast according to the actual needs of customers for its recommendation of one of Taiwan 4 tons of steam condensate gas-fired steam boiler (WNS4-1.25-YQ).
Future development of gas steam boiler is now, due to air quality and the environment has been severely damaged, the Chinese government and relevant departments of this proposed reform, especially in the last few years, we continue to strengthen and urban renewal efforts of management awareness of urban governance continue to increase, there are many heavily polluting factories were forced to shut down or go to the countryside, where coal-fired boiler of this pollution is more serious. Therefore, coal-fired boilers will soon face the fate of being eliminated, but instead is environmentally friendly gas steam boiler. In many areas of the construction of coal-fired boilers, relatively speaking earlier, use of time is relatively long, the use of effects and economic aspects have not reach people's needs, the cost of coal-fired boiler is relatively high, and after use will produce waste water, waste, emissions of harmful substances, so that the use of coal-fired boilers will cause serious pollution to the air. From an environmental aspect is concerned, it will be the first coal-fired boilers will be eliminated. In contrast there would be "waste" gas boiler, it belongs to an eco-friendly boiler. Economically speaking, the general use of more than 5 years of small and medium sized coal-fired grunt no longer have the value of the burned gas, thermal efficiency is relatively low, while the gas boiler coal-fired boiler best alternative. Although the oil-fired boiler thermal efficiency is relatively high, but the smoke pollution in the atmosphere is far greater than the gas-fired boiler, oil-fired boiler and there are also issues related to oil transportation and storage, it lost the advantage of long-term development. Gas boilers have very obvious advantages compared with them. Further, the configuration does not require gas boiler soot blowers, ancillary equipment dust, slag and a fuel drying apparatus or the like, can save the boiler investment. In terms of maintenance, gas boiler is also a very big advantage, a simple gas boiler combustion system equipment, so the group. Maintenance is relatively small, there is a gas boiler slag deposit and high and low temperature heating surface corrosion does not exist, do not need to change the hot fittings and elements of the air preheater surfaces. No matter from which side, gas boilers are the best substitute to replace coal-fired boiler equipment, so the future development of certain gas boiler is much larger than the development of other boilers, gas boilers will set a new record in the future development .
