Di steam boiler safety valve installation and adjustment of safety valves for steam boilers, its importance is self-evident, its purpose is to protect the safe operation of steam boilers, when the medium pressure steam boilers or pipes increases more than the prescribed the value is automatically turned on, the steam boiler safety shutdown. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass 1 ton biomass fired industrial hot water boiler price, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. There are heating and 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. Safety valve is so important, then for its installation, precautions, the author based on years of experience, in particular, are summarized below. 1. The safety valve safety valve should be installed after the installation of the boiler pressure test and adjust safety valve operating pressure at the first fire. The pressure should 7≤2 provided for in section 143 of the National Bureau of Labor Table "Supervision and Regulation steam boiler safety technology" to adjust. 2. Remove the adjustment valve opening pin, remove the cover, loosen the hex lock nut, the adjustment screw is then screwed, to relax or tighten the spring to meet the required pressure exhaust valve. After adjusting tighten the lock nut, and then install the remaining components. When the valve reaches a predetermined set pressure, it should be sealed lead-sealed, unless the check valve, otherwise not allowed to remove the lead seal at any other time. First, when adjusting the safety valve, the water level should be slightly lower than normal water level of the barrel, and ready to enter the water when the safety valve is opened. Second, do not knock any part of the safety valve, the safety valve can only be opened using the valve control lever. Finally, the boiler is absolutely prohibited until the safety valve is adjusted.
In the fierce competition in the market, fast boiler adhere to "not forget the early heart, sustained ingenuity" of the faith, taking the long view, establish and improve a comprehensive overall solution, leading to control market trends, improve the environmental performance of the boiler, make unremitting efforts to build China clean boiler brand.
4 tons of heating boilers price and technical parameters: daily life, often used heating equipment, especially in winter, heating in many cities became much-needed resources, compared to a heating boiler heating effect of the air conditioner is easier to use a product, depending on its heating boiler fuel divided into three types, the first coal-fired heating boilers, the boiler due to the pollution of the air and the environment is relatively large at present has gradually withdrawn from the market, the second biomass heating boilers, Although the new energy, energy is relatively wide usage, but it is restricting the purchase price of equipment and the need for professional fireman operation, so this boiler is often used for bath and large number of hotels and restaurants in the city, the first three kinds of gas heating boiler is different, low price, coupled with the liquefied natural gas in most of these cities are not missing, so it is the most used in civilian areas. This paper to introduce at 4 tons of gas heating boilers, heating boiler manufacturers currently on the market a dime a dozen, the election of a proper and formal model of the manufacturers is very important here to recommend South fast river plant, with 70 years history, began in 1945, is a very professional manufacturer, is currently the largest boiler manufacturing industry base in central and western China, Henan party fast production of 4 tons of gas heating boiler has a dual ability to simultaneously supply heating and hot water, general for urban centers and large bath area, heating area can reach levels ranging from 24000 to 32000 level, if it is lower than atmospheric pressure in certain areas to reduce this area may be, but is not reduced scale.
1.The body adopts corner tube pattern, self-supporting structure, the problem relating to the expansion and the supporting of the boiler is tackled smartly. The supporting structure is stable and compact.
2.The furnace and the descending fuel gas duct adopts total welding membrane water wall structure, which has the features of good sealing, less heat lost and little pollution.
3.Both the air pre-heater and the economizer adopt case pattern structure, which can ensure them be transported in package, so the installation time can be saved and seal ability of the fuel gas duct is strengthened.
4.There is flag pattern heating surface before the high temperature super heater, so the high temperature ability of the super heater can be ensured, meanwhile, the super heater van be operated in the serious fuel gas environment stably.
5.The cross girder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak. And the grates are made by the first-class professional manufacturer.
6.The fuel is sprayed to the furnace, which can ensure the straticulating combustion and suspending combustion, thus the combustion efficiency is enhanced.
