automatic oil fired hot air heater water boiler

Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam boiler can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).

Do you use the right method for the maintenance of fuel-fired gas boilers? After buying oil and gas boilers, many enterprises pay no attention to the maintenance and maintenance in the process of operation, resulting in a great reduction in the service life of oil and gas fired boilers. Then how should the fuel oil and gas boiler carry on the maintenance? The following article for you to do a detailed analysis. When the furnace water is cooled below 70 ℃, the inner dirt will be completely removed, washed clean, all the manhole, hand hole, pipeline valve and so on sealed tightly, and completely isolated from the running boiler with blind plate. After all the alkaline solution has been added, it is injected into the boiler with soft water until the water comes out of the highest part of the boiler and the water supply valve is closed, Pay attention to the mixing average of alkaline solution in boiler.

High resistance steam boiler gas handling system: 1, gas steam boiler pressure gauge, water level gauge, safety, sewage, a water supply valve, a steam valve, check whether the performance requirements, other valves in good condition. Gas hot automatic fired hot air heater water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 2, the boiler Zidongkongzhi device system, comprising a flame detector, level, temperature detection, a variety of interlocks and alarm means, display control system performance states to meet the requirements. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace.

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 automatic fired hot air heater 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.
