Chinese Gas Fired Hot Water Boiler For Heating
Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast boiler R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.
You know how the boiler works? Boiler parameters is a main boiler performance indicators, including the boiler capacity, steam pressure, steam temperature, water temperature and the like. Boiler capacity available rated maximum continuous evaporation or evaporation is represented. Rated evaporation under a predetermined outlet pressure, temperature and efficiency, the amount of steam per unit time of continuous production. Maximum continuous evaporation under a predetermined outlet pressure, temperature, per unit time the maximum continuous amount of steam produced. Steam pressure and temperature parameters including steam boiler, generally refers to a superheater, superheated steam pressure and temperature at the outlet of the reheater and superheater if no reheater, saturated steam pressure and temperature at the outlet of the boiler refers. Refers to a water temperature of the economizer inlet temperature, inlet temperature refers drum without economizer. Boilers can be categorized in different ways. Boiler use can be divided industrial boilers, utility boilers, marine boilers and boiler locomotive; by the boiler outlet pressure can be divided into low, medium, high pressure, high pressure, sub-critical pressure, the supercritical pressure boiler; boiler and by water flue gas flow path can be divided into the fire tube boilers, fire tube boilers and water-tube boilers, fire tube boilers and wherein the fire tube boiler and collectively shell boiler; press cycle can be divided into natural circulation boiler, auxiliary boiler cycle (i.e., forced-circulation boilers), and the combined circulation boiler once-through boiler; by combustion, the boiler chamber into the burner, and boiling Stoker furnace. Water vapor system, feedwater heated to a temperature in the heater, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the water wall downcomer inlet header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam from the superheater to the upper stream drum, continue to become superheated steam endothermic certain temperature (most of the current 300MW, 600MW unit main steam temperature is about 540 ℃), and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere.
Off state of the oil-fired boiler and approach the customer Q: oil-fired boiler flameout what state? How to determine whether the fuel gas boiler flameout it? Henan A fast boiler Company: Table fuel gas boiler furnace pressure instruction value suddenly increases; the furnace black, can not see the flame hole to see the fire; sound disappears combustion furnace; issued extinguishing the flame monitor signal; temperature, pressure abruptly fall, after the water level decreased and then increased, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply is interrupted as a result, oil-fired boiler fuel pressure is reduced to zero. If only a single burner flame, the furnace may also occur flame center deflected off the burner pressure changes; fuel supply is interrupted as a result, the extinguished burner pressure or hydraulic indication may drop to zero, while the other run burner fuel, gas pressure. After this occurs, must be timely treatment to ensure safe boiler. Customer Q: oil-fired boiler flameout, how can I deal with? Boiler Company Zhoukou City lofty Answer: Once a flameout must immediately cut off the fuel supply to the furnace, close the solenoid valve supply (supply and return oil), and then close the fuel supply valve in each operation of the burner. Operation action to be fast, so as not to continue or resume the supply of fuel, causing a risk of malignancy. At the same time, to identify the cause of the boiler flame, troubleshooting discovered, and then start doing the preparatory work. Before starting, we should strengthen boiler ventilation, purge, purge time is more than 5min, then procedures ignition. When the ignition is prohibited sent directly to the high temperature furnace fuel ignition without using an ignition device, in order to prevent dangerous accidents furnace. If due to fan failure caused when the flame, should quickly close the fuel supply line valves each, paying particular attention to the valve not tightly closed due cause fuel leakage. Meanwhile, according to emergency shutdown processing method for ventilating and purging of the furnace and the flue. After the fan resume operation, then step ignition. If only the burner flame, simply close the fuel supply valve to the burner, off throttle small oil-fired boiler, to identify and troubleshoot, and then re-ignition process the ignition. Be sure to quickly deal with properly in order to ensure the safe operation of the boiler.
If within the natural gas boiler wear how to do? Off If there is detailed examination within the natural gas boiler wear how to do? Detailed examination is the key, fuel management is equally important. According to health and time natural gas boiler, we can plan a reasonable wear health check. When using the fuel, we strictly control the particle size of coal and limestone. Should strictly control the size of the bed material. Boiler waste should be handled. Boiler slag to be treated before discharge. Natural gas boiler should be installed in the heat of use, ease of installation. Hot water pipes should not be too long. It should have a good insulating layer. Hot water output to the end of the pipe should be suitably inclined. A water supply source should be equipped with a control valve. Of emissions, natural gas boiler chimney should extend to the outside, the outlet should be higher than the boiler 1.5 to 2M. If you want to reduce the impact on water wall tube, air pressure and air volume can be adjusted appropriately, effectively reduce the wear and tear of the water wall. Check the standby time is generally down or stop. To check items include leak wear, sealing the furnace and the furnace wall of smoke. In the event of wear, the need for timely repair and welding, to ensure the normal operation of the steam boiler. In general, before the gas-fired combustion of fossil fuels need to be filled in the combustion chamber, fossil fuel and bed material and recyclable materials in air speed, strength and stiffness of the shed fully integrated. Wind bottom means upwardly within the core region. Movement of the outer annular region of downwardly along the walls of the flow of boiler water, thereby prolonging the residence time of the coal particles in the furnace. Mineral particles, large amounts of ash and flue gas contains large amounts of fly ash particles, which continue to cause rapid wear of the water wall tube, wall thickness wear thin, resulting in wear and tear.
