china normal pressure electric hot water boiler
Selection of how gas hot water china normal pressure electric hot water boiler? Gas hot water boiler as the name suggests refers to the fuel gas hot water boiler, gas hot water boiler big advantage is energy saving and pollution-free, compact, small footprint, high degree of automation, automatic operation. Gas and oil-fired boiler and hot water boiler electric boiler is compared to the most economical, most people choose as a gas hot water boiler steam boiler, heating and bathing equipment.
First, before regularly shutting down china normal pressure electric hot water boilers and inspecting electric furnaces, the following three aspects of preparation should be done: The main contents are as follows: (1) consult the technical file of boiler retrofit electric furnace registration and understand the use of boiler retrofit electric furnace. In order to make the boiler reform electric furnace inside and outside inspection, the general need to know: boiler transformation electric furnace design, manufacturing, installation situation; boiler transformation electric furnace transformation situation; boiler transformation electric furnace operation history and use situation; Boiler retrofit electric furnace water treatment, boiler rules and regulations implementation, and so on.
2) the preparation for stopping the furnace before inspection. First, according to the maintenance schedule, the furnace shutdown date is arranged, and then the boiler revamping electric furnace is shut down according to the normal shut-down procedure, so that the furnace is slowly frustrated. The cooling method can be adopted by injecting gas to dissipate the sinking water, replacing the furnace water for cooling, and cooling by ventilation in the in-line furnace. When the temperature of the furnace water drops to 70 ℃ 80 ℃, the water can be discharged. Open all the doors. When opening the door hole, prevent warm water, steam suddenly spurts out to burn people. The steam, feed water and sewage pipes in the furnace are separated from the corresponding pipes in the boiler revamping furnace in operation. The baffle used for partition should be strong enough to avoid being bulged out by high pressure media. Break position Clear instructions should be given. The flue which is connected with other boiler revamping electric furnaces should also be reliably separated. In addition, it is necessary to remove the soot and scale on the heating surface of the boiler retrofit electric furnace.
3) preparation of inspection tools and lighting. In order to ensure smooth inspection work, inspectors should prepare the necessary instruments, tools, gauges and safe and reliable lighting.
Recently, the market supervision bureau Zhoushan Development and Reform Commission and the relevant district towns, streets and CMC, 35 steam tons / hour and below the coal-fired china normal pressure electric hot water boilers situation within the region to conduct a comprehensive diagnostic investigation, and to develop in accordance with the relevant requirements of provinces the remediation plan, renovation of existing enterprises to carry out classification boiler eliminated.
Accelerate the phase-out of coal-fired boiler renovation work is to win the Battle of the sky, to lay an important task for the campaign of prevention of pollution. In recent years, Putuo District of Zhoushan City, to speed up the adjustment of energy structure, and actively encourage enterprises to adopt "coal to gas," "coal to oil" as well as central heating and other measures. By the end of 2018, the district has completed the elimination or modification for 10 steam tons / hour coal-fired boilers 175 units, effectively promote pollution reduction work.
According to "Zhejiang win the Battle of Blue Sky three-year action plan" requirements, by 2020, the province will be basically eliminated 35 tons of steam / hour and coal-fired boilers, more than 35 steam tons / hour of high pollution and energy-saving ultra-complete boiler low-emission transformation. Next, our region will be based on the unified arrangements of provinces and cities, and actively practice the concept of green development, continue to promote the 10-35 tons of steam / h coal-fired boiler out of rectification work to further improve the air quality in Putuo District.
Distinction gas steam china normal pressure electric hot water boiler and a conventional coal-fired boilers and gas steam boiler (1) in a conventional coal fired boiler should be prechamber through grinding equipment, coal should be produced for combustion injected into the furnace, the entire combustion process in furnace and in the form of a suspension. (2) as long as the gas steam boiler biomass fuels open, dried and crushed, the helical feeder to the air before it is blown into the top of the combustion grate vibration. After burning the soot removed from the baghouse gas steam boiler. 2, different air supply preheating. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees (1) coal-fired boiler air preheater flue at the bottom, below the economizer; using flue (2) temperature of the air supply end of the cigarette is heated, different from a conventional boiler, the feed gas steam boiler air preheated by the air preheater flue gas cooler and the two parts to feed water as a medium to absorb heat of the flue gas, conveying air into the furnace. Warm air supply system for a gas steam boiler is controlled by adjusting the supply air temperature of the heating water flow can be provided by adjusting the electric charge of the bypass track circulation water through the valve and the air preheater flue gas cooler bypass control. Water heat exchange section, cooling water heated through the air preheater and the cold air delivery fan; then, this part of the water continues to flue gas cooler, flue gas by exchanging heat with water in the flue gas cooler, water heating, cooling the flue gas. In the bypass, a bypass flue gas cooler and another bypass air preheater, both have their own electrical control bypass and isolation valves. When the flue gas cooler exit gas temperature is too low, the bypass isolation valve is opened, water does not pass through the flue gas cooler, flue gas heat exchanger is not performed to ensure the flue gas cooler outlet gas temperature is not too low smoke corrode gas cooler. In order to enter the flue gas cooler feedwater temperature is not too low, when the air preheater outlet water temperature is below a certain temperature, it opens the bypass, supply cool air can not be heated, the water temperature is too low to prevent the influence of the flue gas cooler work . But also to ensure the temperature of the flue gas through a gas steam boiler precipitator. 3. The coal-fired boiler flue gas fired boiler bag filter should be used for desulfurization libraries to ensure the emission of pollutants lower than the standard. 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. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. However, biomass combustion flue gas are different. Biomass fuel of low sulfur and nitrogen content, only through the biomass filter before discharge into the atmosphere. However, the carbon content of fly ash produced by the combustion of biomass, coal-fired boiler boiler efficiency is better, but the carbon dioxide content in the greenhouse can be reduced. Under the same nitrogen content of the fuel, the nitrogen oxides emission concentration of boiler far below the emission standards for coal-fired boilers. The problem should be noted that operation of the gas boiler. From the operational perspective view of the gas boiler, the operation of the gas boiler should note the following: The actual fuel consumption of the boiler operation, the amount of oil to the adjustment screw feeder. Unburnt fuel in the furnace, induced draft fan and the blower can not be stopped. Sudden power outage in operation, must be promptly removed fuel furnace. Not add biomass fuel before the shutdown. When the furnace stopped, there is no need of the bank up a fire. When the fuel on the grate exhausted, drum induced draft fan may stop running.
