china electric heating water tube hot water boiler seller

To accelerate the low nitrogen transformation gas china electric heating water tube hot water boiler seller in each area of ​​Xian, October 23, 2018, liberation of the door street in charge of leading Korean right lead a public person with low nitrogen regional transformation slow the unit door butt again, and supervise the various units to speed up progress, by the time limit to complete the task of transformation.

1, Imperial Square area, parking building, Suntech Lane three projects reflect seven plots site inspections carried out two times, road construction site clean and moist, well-covered, site supervision and regular opening spraying dust and other facilities, strict implementation of air pollution control measures.

2, the region west of Seven Road, Sheung Tak Road, west along the eight dining pollution checks to ensure that all food and beverage outlets normal use of fume purification facilities, and urge all stores on a regular basis to do routine maintenance.

Hot water china electric heating water tube hot water boiler seller heating mode, which has several? Indirect Heating boiler water: high temperature hot water supply system, and by directly converting the high temperature hot water heat transfer station is a low temperature and a low temperature heating system running hot water. The system contains two separate high and low warm water circulation, two lines standing pressure. Due to the heating system in their assembly separate water circulation system, high and low temperature circulating pump system, a separate area, the presence of equipment investment, operation maintenance, staffing, secondary energy consumption, infrastructure investment, covers and many other issues. Daily fuel tank hot water boiler provided steam heating means and electrical heating means, hot water boiler when cold start ignition furnace, because there is no electric heating steam, hot water boiler when the ignition is successful and handover immediately after the steam generated steam heating. Indirect heating of running hot water boiler with high viscosity heavy oil, in addition to a mechanical pulverizer means daily heater heating the oil in the tank to supply the service required corresponding to a temperature suitable viscosity, the heavy oil is pumped to Front heater - secondary heater again, the latter is to meet the needs of high temperature water boiler oil atomization nozzle. Thus, the heavy oil mainly for secondary heating boilers burning fuel, the other part is small in the circulation tank return line back into the household.

After electric steam china electric heating water tube hot water boiler seller shutdown, how maintenance? When long-term disabled electric steam boiler, furnace should pay great attention to external corrosion and maintenance problems. First, after power shutdown cooling steam boiler, the ash must be thoroughly cleaned and the heating surface fouling the upper grate, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As for anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover, valve steam, the water pipe change must cut lime powder should be replaced.

Horizontal pressure steam china electric heating water tube hot water boiler seller protection 1. 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. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. When the boiler pressure exceeds the vapor pressure protection rating, it is necessary to protect the chain: the furnace is shut down and stop working combustion system; it can change the nozzle, a single stage or two stage combustion, the amount of oil can be adjusted, thereby reducing the pressure, ensure the safe operation of the boiler. 2. Protection of the same pressure level of oil (gas) steam boilers, the use of multiple protection: a pressure controller typically uses two pressure controllers, electromechanical conversion device pressure signal into an electric signal. Its function is different from the high and low signal to the electrical switch, for automatically controlling an external circuit or interlock protection. Common electrical contact manometer and pressure controller can issue an alarm overpressure vapor pressure combustor and cut off, the pressure controller adjusts single or double fire burning fire based on the actual pressure, the pressure controller may overpressure the steam pressure alarm limit is reached close the burner when the limit is reached. For large burner, the fuel can be adjusted according to the amount of pressure, the pressure is always maintained in a stable operating state. 2 safety valve safety valve last line of defense to protect the boiler. When the boiler pressure exceeds the limit, according to the set pressure relief valve design, exhaust pressure to ensure the normal operation of the boiler.
