Some little knowledge about the daily gas hot water boiler on the application of the hot water boiler depending on the divided fuel: electric water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; pressure can be divided according to whether pressure hot water boiler and hot water boiler two kinds of pressure, we usually refer to the hot water boiler refers to the pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler . At the same time, it was conducive to a different division of the hot water boiler classification, so that the field of use of hot water boiler is also very extensive. For example, there are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Hot water boiler is the production of hot water boilers, heat or other means of thermal energy released by burning the fuel (e.g., electricity, solar energy, etc.) The water was heated to a nominal temperature of a thermal device. The remote can accurately monitor steam boiler combustion process. Degree of automation, all kinds of perfect security. Optional high-quality imported low NOX burner, combustion, are environmentally friendly products. So, these two have for each boiler water production benefits and advantages, will give you specific explain in detail the following: hot water boiler can provide a lot of hot water, wet steam and superheated high-pressure steam, but it can the pressure to achieve only up to 32bar. In today's technical conditions, hot water boiler can achieve temperatures can reach 240 deg.] C, steam flow can reach 45t / h. From the viewpoint of the current epidemic, there is provided the use of wet steam is flash steam boiler ideal solution: hot water boiler provided with wet steam (relative humidity of 2% to 3%) compared to the wet steam boiler to provide steam quickly relative humidity only 0.5%, so that the steam pipe can reduce the harm caused by steam condensation, has a very good thermal conductivity in use. Key to efficient energy-saving steam supply is often associated with the use of steam are closely linked: the occasional use of steam or continuous steam Similarly, if the boiler has a longer downtime, must also consider disabling factor?. Quick steam boiler at startup embodies the advantages of energy-efficient, and can save an average of 5% to 11% of energy; and a hot water boiler in a normal, energy loss is still under continuous operating conditions: heat by radiation and chimney energy loss. And hot water boiler after discontinuation of a long period of time, take a long time to recover back to normal working condition.
Work and family considerations boiler shutdown boiler inspection carried out maintenance before restarting operation, the need for a series of maintenance work, combined with the user experience and learning references, be aware of the following specific boiler maintenance work and family considerations. 1. Preparation (1) before the boiler before the boiler equipment maintenance inspection, as in normal shutdown program is stopped, slow cooling, water circulation and ventilation through the furnace, and gradually lowering the temperature of the boiler furnace. When the temperature dropped below 80 ℃, the door opening open various checks on the boiler. Prevent steam, hot water or cigarette burns when opening the door opening. (2) Steam test boiler feed water, should be separated from the sewer line with the respective other operation of the boiler. Blind for a separator plate should be sufficiently strong to avoid high pressure medium in the broken drum is operated. This clearly indicated the blocking position. Combustion chamber and the flue (3) Check the boiler should be separated from other operation of the boiler. Flue and ventilation doors must be closed tight after separating. 2, preparation of the pressure vessel (1) before the container inspection prior to examination, to be completely cut off the connection tube between the container and the gas pressure or other equipment, particularly equipment using flammable or toxic media. Not only must the valve is closed, and must be sealed with blind plates, so that the valve leaks, resulting in leakage of flammable or toxic gases into the vessel, fire, explosion or poisoning. (2) all media in the container to be discharged. Containers containing flammable, toxic or suffocating medium should be cleaned, replaced or sterilized, by sampling and analysis. A power supply associated with the container, such as a container with a stirrer, reversing mechanism, etc., must be cut off, and a clear flag indicating not allowed to connect. 3, a boiler maintenance considerations are (1) Note ventilation and monitored prior to entering the drum, the container, the drum must be opened, all in the hole hand hole in the container and the collection tank, the air convection period and adequate ventilation. When entering the drum and the container inspection, one must monitor the external device. Before entering the combustion chamber or flue must also be ventilated. (2) Note that the detection of electrical safety in wet flue drum and when the lighting voltage should not exceed 24 volts, with electric lighting. In dry flue, using appropriate security measures, it may be no more than 36 volts lighting voltage. When entering the test vessel, should be used no more than a low-pressure proof lamp voltage 12V or 24V. When the supply voltage detection equipment and maintenance tools than 36V, good insulation must be reliable grounding cord. Boilers and containers should not be used flame. (3) removably connecting member pressing the forbidden band in the inspection of boilers and pressure vessels, pressure if the fastener member needs to unload or screwing, must fully release the pressure, before it can be. Bolts or other fasteners can not be tightened or unloaded at the boiler pressure, in order to prevent accidents. (4) prohibits self-test instead of the hydraulic pressure to the boiler pressure vessel test pressure test generally use water as the pressure medium, there is no gas as a pressure medium, otherwise it is very dangerous. For structural reasons the like, water can not be used as a pressure medium test individual containers, when instead of hydraulic pressure in accordance with design requirements, should be thoroughly checked before the test, check the strength and reliability of the measures taken. Prior to implementation should conscientiously implement the design in accordance with the provisions of, and prior consent of the security sector.
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 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.
Radiator is an important accessory good quality low pressure horizontal electric steam boiler radiator heating is an important accessory electric steam boiler heating, how to make more warm radiator, Guoxin Industrial Equipment listen to your support three measures. 1, to increase the area of heat radiators, trying to improve the heat radiation amount, the area increases the users are many methods employed, we only need to add to its outer wall to help sheet, which can effectively increase its thermal effect, but also to improve the overall temperature of the room. 2, reduce the thermal resistance! Use of gas boiler radiator will certainly generate thermal resistance, thermal resistance and to know the amount of heat is inversely proportional. To minimize thermal resistance, can be a corresponding increase in the rate of heat dissipation, thereby improving the thermal effect. 3, by increasing the air flow through the chamber, increasing the indoor temperature. Through the gas boiler radiator installed in ventilated place, then its effect is a lot better.
