What is a thermal power station boiler manufacturers in china? Does the normal pressure boiler need annual inspection? Thermal power station boilers, commonly used in power plants for power generation and heating boilers. Moreover, the capacity of this kind of boiler is relatively large, and the main unit is usually 300 MW. Normal pressure boiler this kind of boiler, it is for the general container and not belong to the pressure vessel, therefore, does not need to carry on the annual inspection.
The party soon provide us with three hot water boiler manufacturers in china output foot, gas combustion, efficiency is very high, for us to save a lot of fuel costs. Moreover, these hot water boiler can be achieved by adjusting the full 24 hours a use hot water to meet the daily needs of old people. --customer feedback
Before being put into operation, a detailed study of technical personnel to study accompanying documentation and various other technical information in Note 1. Henan Henan former boiler manufacturers in china manufacturers boiler boiler manufacturer boiler running, in-depth understanding of a variety of technical performance of the equipment. After work out procedures and equipment used, Henan boiler manufacturers boiler operator or use the necessary technical training, in order to deliver the boiler operation. 2. The maintenance personnel should be strictly in accordance with the relevant regulations of the equipment for maintenance, the equipment is in good condition. 3. When the boiler in operation, any of the following circumstances and ineffective protection, emergency shutdown should: (1) boiler water level below the water level of the lower edge of the visible, increasing water supply and other measures, but the water level continued to decline; (2) Henan boiler manufacturers boiler water level exceeds the highest visible level (full of water), turn on the water can not be seen by the water level; (3) water softener system failure, not water to the boiler and boiler water level below the water level gauge the lower edge of the visible; (4) Henan boiler manufacturers boiler circulation pump fails can not operate properly; (5) Henan boiler manufacturers boiler component damage, endanger the operating personnel safety; (6) boiler water temperature abruptly rises out of control; ( 7) other abnormal situation threatening Henan boiler manufacturers boiler safe operation. 4. accident tight shutdown for lack of water, exhaust prohibited, the operation of the boiler feedwater and blowdown Henan boiler manufacturers. 5. Henan boiler manufacturers boiler room should be well ventilated. 6. circulation pump normal operation after the start-up burner, circulation system valve should open. To prohibit start-up burner, boiler manufacturers Henan boiler to be warmed and then start the circulation pump or the valve is opened suddenly. 7. boiler circulating pump failure and stop running the boiler protection system is not functioning boiler caused a "dry", the non-boiler feed water to the boiler factory in Henan or circulation pump. 8. shutdown, the shutdown button press on the operation screen, a combustion burner is stopped, closing the intake valve. Disconnect the power to the controller, disconnect the main power boiler.
Technical characteristics premix condensing boiler manufacturers in china furnace condensing premix premix combustion characteristic technical features: refers to a gas burner thoroughly mixed with enough air prior to the burner, it is no longer necessary to supply combustion air to the combustion process . 1) the combustion flame characteristics: flame propagation speed, high strength hot combustion chamber volume, generally up to 28 ~ 56x103kW / m2 or more, the excess air coefficient is very small, typically α = 1.05 ~ 1.2, the combustion temperature is high, low nitrogen oxides emissions. But poor flame stability, prone to tempering, tempering is prevented, so that as the gas flow velocity to be uniform field, to ensure that the air flow velocity at each point are greater than the flame propagation speed at the lowest combustion load. At the same time, a uniform air distribution surface also ensures the uniformity of the burner flame to avoid flame on the burner surface is too long, contact with heat exchanger surfaces resulting in incomplete combustion. 2) premix combustion mode effective to reduce the emission of pollutants, such as: the reduction of nitrogen oxides, carbon monoxide emissions. Features condensing heat exchanger of the main characteristics of the entire cast aluminum water-cooled design, the combustion chamber is surrounded by watercourses, effectively absorb heat, cooling the flue gas. The thermal conductivity of aluminum is 8 times that of stainless steel (aluminum: 130W / m ℃, stainless steel:.. 16.2W / m ℃), it gives greater leeway in the design of the combustion chamber and waterways. The corrosion resistance: aluminum is a reactive metal, under natural conditions, the aluminum oxide surface layer can be formed of a dense, acidic corrosion can be effectively prevented from corrosion and oxygen. China's abundant reserves of aluminum, lack of demand, leading to low prices, low melting point of aluminum, with a high fluidity at high temperature casting, casting and machining good performance. Flue gas top-down, bottom-up flow. Aluminum heat exchanger in a combustion chamber with a needle-like protrusions, grooves waterways with a heat exchanger, to optimize heat transfer effect, and effectively increase the heat load of the heat exchanger unit.
