Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
9.4MW YQW gas-fired thermal oil heater for clean-energy industryThermal oil heater is a kind of new heat energy equipment with low pressure and high temperature, playing an important role in various industries. Huagang Gas Group is a sino-foreign joint venture enterprise, which established by Kunlun Energy Company Limited and Huabei Oilfield Company. The company is engaged in natural gas, liquefied petroleum gas, blast furnace gas and so on. Due to the stringent quality requirement for pipeline gas in China, all natural gas needs to be decarbonized and desulphurized. A high-quality 11 ton portable steam boiler dealer is one of the key equipment for the productive process. With the development of global environmental policy, the demand of clean energy is growing with each passing day. Huagang Gas Group has carried out public bidding to purchase one set of thermal oil heater to meet the production need. Relying on rich experience and powerful comprehensive technology strength, ZOZEN won the bid and provided 9.4MW YQW series thermal oil heater for them. The heat exchange surface of the thermal oil heater adopts multi-loop round coil tube structure, which features high security and sufficient heating surface. The waste heat boiler, air pre-heater and economizer are installed on the tails of the thermal oil heater to effectively improve the thermal efficiency (The thermal efficiency of ZOZEN thermal oil heater can reach up to 95%). Moreover, this kind of thermal oil heater adopts perfect running control and safety monitoring device, which can control working temperature strictly and guarantee the safe operation.
Check the work before the start fuel gas-fired boiler in order to protect the safe operation of the gas boiler, improve operational efficiency boiler, make sure to check the work before the boiler starts, every detail can not be ignored. 1, check the safety accessories, thermal instrumentation, electrical instrument should be intact; 2, check the connections, whether the water leakage and the furnace body line; 3, check the waste line, the water line, return line should be smooth; 4 , should check the line voltage is 380V, the fluctuation should be within ± 5%; 5, oil-fired boiler and a filter pump check whether normal oil, gas boiler check the gas pressure is normal, not too high or too low, the oil supply opening valves; 6, check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Water Supply System opens each valve (including the water pump and water valve before and after the boiler); 7, check level gauge, the water level should be in the normal position, to prevent false water level, if the water can be manually Sheung; 8, check the pressure conduit the valve must be opened, the wind deflector must all flue opening; 9, each knob inspection control cabinet are in their normal position; 10, a check valve should be 11 ton portable steam boiler dealer in a closed state, the hot water boiler circulating pump valves should be closed state; 11, check water softening equipment is operating correctly, create a variety of indicators of soft water meets national standards. Carefully do the above inspection, the basic conditions for the fuel gas boiler safe and economic operation.
The temperature difference between the wall surface of the vertical 11 ton portable steam boiler dealer steam is generated during the vertical steam boiler generates steam, and pressure in the heating, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the temperature of the lower wall, and wall thickness of the vertical bubble there is a temperature difference between the walls, i.e., the inner wall temperature of the bubble is higher than the temperature of the outer wall, the wall temperature is higher than a temperature lower wall, an outer wall and inner wall temperature is higher than the temperature of the inner wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature of the lower wall , the wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature at the wall, the inner wall temperature is higher than the outer wall temperature. 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. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. In order to prevent excessive thermal stress, it is necessary to slow the vertical steam boiler booster. Vertical steam boiler ignition and boosting process conditions steam parameters, each component level and also changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange closely monitor vertical steam boiler various instruments directive professionals change. Since the vertical steam boiler water temperature continues to rise, the metal wall temperature of the bubble and the evaporator heating surface begins to rise at any time, it is necessary to pay attention to temperature and thermal stress of thermal expansion of the bubble, since the bubble wall thickness is relatively thick, so vertical the main problem in the steam boiler heating thermal stress. At the same time, also considering the overall thermal expansion problems, especially vertical tube steam boiler heating surface, since the wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused.
