small blast furnace gas fired steam boiler

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 small blast furnace fired 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.

Leakage Protection boiler manufacturers tell you tell you the importance of the importance of the boiler manufacturers leakage protection ----- i.e. drain leakage protection automatically cut off power; i.e., when the boiler water temperature overheat protection ultrahigh temperature reaches the alarm automatically stops the burner and alarm ; i.e., protection of the secondary superheater boiler housing temperature exceeds 105 deg.] C, operating system manufacturers to automatically cut off the boiler-like secondary circuit, the boiler is stopped; i.e. excellent anti-dry protection level electrode rod real-time monitoring water level, the boiler water level reaches the other reasons , below the low water level, the boiler stops working, to prevent the occurrence of dangerous dry. Glass wool insulation for whole body type, light weight, good thermal insulation effect, and less heat loss. White color board packaging, nice, closed Haonai corrosion, mechatronics, small footprint, and easy to use. Gas-fired boiler widely used in supermarkets, hospitals, schools, hotels, residential, bath center, fully automated for the user to provide bathing water or heating, domestic hot water. CWNS gas hot water boiler 1, the boiler hot water boiler manufacturers computer controller, all the functions are stored on a magic smart chip, a gas boiler small blast furnace fired steam boiler power key, automatic timing, temperature operation, the user can set startup, shutdown time, the setup is complete, no special duty to save time, and effort. 2 gas boiler, burner configuration imported brands, high degree of automation, automatic purge controller according to the instruction, the electronic auto-ignition, spontaneous combustion, air oil (gas) automatic ratio adjustment, security and stability performance, good combustion. And there are flameout protection device, ensure safe operation. 3, the inner fire tube inserted spoiler retardant, smoke slow speed, to strengthen the heat exchanger, the temperature of the flue gas discharged from a low smoke chamber, reducing heat loss and save fuel. 4, large font display temperature, easy to grasp and boiler operating conditions of the system, the water temperature can be freely set from 10 ℃ to 90 ℃, automatic boiler or heating system to provide users with life, bath with hot water.

Accessories szs system and boiler water tube boilers which (1) the fuel system the fuel system of pumps pumping fuel from the fuel tank to the day tank, is then withdrawn from the daily tank fuel pump, through a pressurized, heated, and sprayed into the filter oil atomization. This system is usually divided into the border daily service tank and oil supply system and fuel system. (2) feedwater, condensate water, steam condensate system piping system comprising pipes and valves and piping and other equipment from the deaerator. Steam system comprises a steam pipe and various valves. (3) the ventilation system features a ventilation system external air into the furnace for combustion of fuel, and the products of combustion (flue gases) discharged from the boiler to the atmosphere. In the process of air and flue gas flow, there will be a variety of flow resistance, if the natural ventilation generated by a chimney to overcome the resistance to flow, called natural ventilation. Obviously, this ventilation air flow generated is small, can be improved by increasing the height of the chimney natural ventilation. Using a fan to overcome the flow resistance of various ventilation systems, called mechanical ventilation. Mechanical ventilation is divided into positive pressure ventilation, ventilation and negative balanced ventilation. The so-called positive pressure ventilation means for sending air to the boiler and the flue gas discharged from the boiler to the atmosphere. Primer furnace boiler flue gas exhaust blower suction chamber, known as negative pressure ventilation. (4) boiler auxiliaries and monitoring instrumentation and monitoring instrumentation, boiler accessories boiler safe and economic operation are necessary, including: (A) as an annex to ensure the safe operation of the boiler: water level gauge, safety valve, pressure gauge and thermometer indicating steam parameters ; B) combustion supervision parts: pressure gauge, carbon dioxide indicator, oxygen table, smoking view mirror.
