Factory supply medical usage oil hot water boiler
Gas-fired steam boilers can be cleaned during cleaning using efficient and environmentally friendly non-corrosive detergents. This will cause the tube to expose the primary color of the metal and reduce the impact of dirt and bio-algal sludge. After ignition of gas-fired steam boiler, attention should be paid to observing the furnace temperature and the temperature of the main steam. With the increase of main steam pressure, the flue gas temperature of boiler is obviously increased after ignition. If the temperature does not rise, you should go to the scene immediately to inspect the oil gun fire. The scale thermal conductivity of a gas-fired steam boiler is only 1/10 of that of steel. This hinders heat transfer when it scales on a heated surface. In order to keep the boiler in use The output shall increase the temperature on the combustion side. The increase of outlet temperature of gas-fired steam boiler increases the loss of gas-fired steam boiler, and the scale on the water wall of equipment will effectively reduce the heat transfer effect, which may lead to the increase of the temperature of water wall and the burst of water wall. When a gas-fired steam boiler is in operation, a series of chemical and physical reactions will occur in the furnace. In use, it will effectively form a hard and dense scale on the heated surface, which will directly lead to its heat exchange. The reduced efficiency and corrosion due to scale will reduce the heat absorption of gas-fired boilers.
Steam boilers What is the function? Too much in the form of steam boilers, took an ordinary four tons fast load steam boiler, for example. There are heating and factory supply medical usage 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. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Works steam boiler water is heated and converted to steam in the steam drum, the fire gives off heat in the furnace. Let me talk boiler, say the pot. This boiler is a water-cooled drum boiler. Around the drum in the two regions is provided two return tubes pyrotechnics, smoke box and in front of the drum to turn back. In the boiler drum and the lower connection between the tank, a downcomer and a cooling pipe, constituting the framework of the combustion chamber. An upper drum provided with a vapor separator, in order to reduce the outflow of water from the steam. Heating surface of the pot to the drum, and a lower cooling pipe pyrotechnic tube. A combustion section and drive means consisting of a chain grate, a combustion chamber pot grate frame composed of frame. It is surrounded by refractory material. By the combustion of the coal into the coal hopper, the thickness of the coal seam is controlled by the gate, while the air is sealed in front. Blast into the lower part of the combustion chamber is the place, this big boiler resistance, it is necessary to force the blast. Burning ash through the rear grate Eagle iron is discharged, and the outside of the furnace through the slag discharged from the device. Smoke from the rear of the boiler, the boiler return pipe from the first pipe, the second pipe from the reflux to the back, and then enters the precipitator ash is then discharged through the chimney draft fan. Induced draft fan is not only the smoke emissions, but also the negative pressure necessary for operation of the boiler. Steam boiler is a pressure vessel, the safety device is essential. Basic boiler water level gauge, pressure gauge, safety valve, thermometer, water can be added at an upper portion of the electric pump pressure, when the pump power and steam may also be used. Boiler water must be softened, and water treatment equipment.
Basic requirements for thermal control of fuel gas boiler rooms 1. Main characteristics of fuel-fired Gas-fired Boiler the main difference between oil-fired gas-fired boiler and laminar combustion coal-fired boiler is that the combustion system is different, mainly in the fuel property and combustion mode. The combustion system of the fuel-fired gas-fired boiler has the following two characteristics: 1) if the combustion process is not controlled properly, a large number of combustible mixture can be formed in the furnace, and when the mixture is deflagration, it may cause the furnace explosion. Causing serious property losses and casualties. 2) the combustion mode of fuel-fired gas-fired boiler is space combustion, the combustion speed is faster and the load response is quick. 2. Self-control of oil-fired gas-fired boiler The control requirements are in accordance with the combustion system of the fuel-fired gas-fired boiler, and the basic requirements for the automatic control system of the oil-fired gas-fired boiler are as follows: (1) the reliable system is configured to prevent the explosion of the oil-fired gas-fired boiler. When designing the automatic control system of oil-fired gas-fired boiler, the reliability of the system must be given priority consideration, and if necessary, the design mode of setting the protection system and the detection control system separately can be adopted. In order to improve the reliability of the control and protection system, it is necessary to configure the necessary backup manual control and double indication of important parameters in the selection of the microcomputer control system. (2) strict procedures should be taken to control the start-up of oil-fired gas-fired boilers. Program control is adopted to strictly detect fuel system, air supply system and flame monitoring system in the process of starting and stopping, so as to avoid failure in the process of starting and stopping furnace. (3) timely alarm protection should be based on specific conditions. Select the following alarm and interlocking protection items related to combustion system: 1) alarm and interlocking protection of drum water level. 2) Boiler pressure overpressure (factory supply medical usage hot water boiler outlet temperature overheating) alarm and interlock protection. 3) flameout interlock protection. 4) low oil pressure interlock protection (oil fired boiler). 5) High oil temperature interlock protection (oil fired boiler). 6) low oil temperature interlock protection (oil fired boiler). 7) low Gas pressure interlock protection (gas boiler). 8) High gas pressure interlocking protection (gas boiler). 9) low wind pressure interlock protection. 10) burner flange limit to open correlation lock. 11) combustible gas leakage alarm. 12) earthquake interlocking protection. (4) when the rapid system responds to the abnormal flame extinguishment in the operation of the fuel-fired gas-fired boiler, the automatic control system is required to cut off the fuel supply rapidly and prevent the fuel from entering the furnace, so the automatic control system is required to respond quickly enough. (5) when the load of the fuel-fired gas boiler changes, the response speed of the fuel regulation is higher than that of the air supply system. Hurry up. When the load increases suddenly, the increase speed of fuel is greater than that of the corresponding air quantity, which results in insufficient combustion and black smoke, and when the load decreases suddenly, the reduction speed of fuel is fast, and the oxygen content of exhaust smoke is too high. For the small boiler controlled by bit, the increase or decrease of combustion should match the increase or decrease of air volume, otherwise, the ignition may be extinguished. Therefore, combustion and air control should be considered in the design of automatic control system. (6) for the automatic control system of gas-fired boiler, the explosion-proof instrument should be used in the field instrument.
Comfortable life of people is inseparable from the northern winter heating boiler, normal, stable heat source is vital to people's lives. But the attendant is an increasingly serious environmental pollution problems, the implementation of coal to gas policy without delay, using the gas factory supply medical usage hot water boiler is the general trend. In order to achieve green heating, the National Tourism Administration Service Center decided to phase out the existing coal-fired boilers, the introduction of clean and environmentally friendly gas hot water boiler. Fast boiler with their own strong comprehensive strength and rich experience in the heating industry cooperation gained the trust of the National Tourism Administration Service Center, and ultimately provide a vacuum hot water boiler (T6-2800 2 sets of 2.8MW by fast Boiler ).
