oil hot water boiler suppliers

Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast boiler. Thus, when the company in the purchase of the product boiler, and fast boiler almost hit it off, by the party to provide a fast 6 tons of steam integrally condensing gas steam boiler (WNS6-1.25.Y.Q).

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 (hot water boiler suppliers 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.

After electric steam boiler shutdown, how to carry out maintenance in the 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.

1, Safety Precautions: 1 gas hot water boiler suppliers room should comply with fire safety requirements, and equipped with the necessary fire-fighting equipment. Storage of flammable materials, such as oil, wood and the like. Non-smoking room, non-smoking room, non-idle personnel and miscellaneous personnel. 2. The operator should be familiar with the structure and performance of hot water boiler components, specifically the installation location and function of the main components, prohibit untrained personnel into the boiler room operation device. 3. A gas water heater enters the room the operator must carry combustible gas, before closing and power, gas chamber must be checked to ensure that the concentration of the gas chamber is not higher than 0.5%, is prohibited switch off transmission. At the same time, we must take effective measures (open windows and doors) for ventilation. 4. Before starting, the supply voltage must check meet the requirements, no phase ground fault or damage, electrical control equipment and mechanical devices meet standard requirements, trouble-free start. 5. Before you start circulating pump must ensure that the system of heat and hot water valve intact, hoist flexible, good pressure gauges, thermometers and other facilities, piping systems leak, the water supply tank water level to the required standard. Otherwise forbidden to open the device. 6. Before starting, you must check the gas supply system to ensure no leakage, pressure is normal, compliance (> 8KPa). If the air pressure is abnormal, the ban starts.
