Four advantages pressure hot water boiler pressure hot water boiler as a commonly used heating equipment, widely used in various occasions to people's daily lives has brought great convenience, not only saves a lot of resources and created high economic efficiency at the same time on the market has also been warmly welcomed by many users, and has been in demand ever-increasing trend, while customers adhere to the selection pressure hot water boiler is mainly because of this four technological advances of this type of boiler. A cheap price pressure hot water boiler itself is not high, coupled with the use of natural gas and other fuel prices in recent years also declined, pressure hot water boiler efficiency, so that the selection pressure hot water boiler the lower cost. In addition durability of high pressure hot water boiler and maintenance and it is very simple and convenient, so use better economy. Second, the high pressure hot water boiler efficiency using three layout design process, which is wet-like structure so that the heated area of great pressure hot water boiler, while the flue gas condensation recovery tail can be well controlled high temperatures generated when the exhaust pressure hot water boiler so that the use efficiency of the boiler is improved. Third, the security and stability of good pressure hot water boiler brand manufacturers at the factory is equipped with an alarm system for the boiler temperature, overpressure alarm systems, alarm systems, and leaking water and flame protection systems and other safety accessories, so that pressure hot water boiler safety when stronger, more stable. Fourth, the small size pressure hot water boiler generally uses quick structure, the bottom of the package boiler have adopted extremely rigid material, more compact size more convenient transportation and installation space requirement for the use together with not high in suitable for use in a variety of different environments. These are the four main advantage of pressure hot water boiler, these advantages are also a lot of customers are willing to choose and stick with the main electric hot water boiler heating under pressure. But pressure hot water boiler in actual use requires the operator to be checked regularly timed debugging, for safety near to promptly check its integrity in order to ensure a more secure boiler operation.
Fangkuai Group has more than 60 independent intellectual property rights, advanced clean fuel boiler manufacturing technology, and jointly established a clean fuel boiler production, research and research cooperation base with Tsinghua University and Xi'an Jiaotong University. An enterprise with a R & D and test center for clean fuel boilers. The thermal efficiency of “Fangkuai” boilers can reach 107%, which has been included in the national special equipment energy-saving catalog. The company developed ultra-low nitrogen full premixed combustion condensing boilers and ultra low nitrogen emission fuel gas boilers, which are developed by the company using Ultran condensation technology.
The inlet speed of gas-fired hot-water boiler before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). Straightness of pressure pipe If the diameter is too small and the length is too long, it will affect the dynamic transmission of pressure measurement and increase the dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The pressure tap shall be perpendicular to the flow of the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated steam boiler, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring the gas pressure, remove the pressure splice from the upper part of the pipe to prevent dust and dust in the gas The droplets enter the ignition line. The installation site of the electric heating steam boiler pressure gauge (pressure transmitter) should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, and should be easy to observe, repair and ensure safety. Insulation should be laid on pressure pipes in high temperature media to avoid burning during flushing. Pressure lines are equipped with needle valves (for cutting off pressure in the event of pressure line failures during operation), auxiliary needle valves (for use with instruments, stopping, replacement), condensing coils and elbows (isolation elastic elements from high-temperature media), Easy to install sealing gaskets) as well as sewage valves and sewers. For special pressure measurements, it's still pressing. Install discharge valve, isolation room and so on in the force pipe.
Hot water boiler 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.
