Gas-fired steam 1ton industrial fired boiler safety valve from installation to use, it must remain vigilant safety valve is one of the most important components of the gas steam boilers, boiler probability of the risk occurring due to various incidents can effectively suppressed. This article focuses on the safety valve from installation to use several important considerations, we do not ignore the use of gas when it steam boiler. A Notes 1 safety valve, the safety valve should be mounted vertically in a high position in the pot business, set box. 2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. 4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm. 5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve. 6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. 7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. 8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve. 9, separable economizer outlet, the steam superheater outlet valve must be installed.
Finally, He Jinping, vice governor visited our laboratory cleaning 1ton industrial fired boilers, boiler shocked layout in the laboratory, the enterprise to acknowledge in-depth study of the safe operation of the boiler. Prior to departure, He Jinping, vice governor, said: "Your company is active in this research, visit the highest gold content of science and technology, value-added security strongest companies in the field of corporate research you safe operation of special equipment, has exceeded the government. the widespread perception boiler products.

How many calories Horizontal one ton steam 1ton industrial fired boiler needs? 1 ton steam boiler, require 600,000 calories, biomass is the most economical fuel. 1 t of steam boilers, 600,000 calories needed, is converted into fuels: diesel 58kg / hour, i.e. cost of diesel and 466 / hour; biomass particles 150kg / hour, the cost of 165 / hour. 697 electrical degrees / hour, i.e. cost of electricity 697 / hour; gas 75m3 / hour, i.e. cost of natural gas 375 / hour; 120kg of coal / hour, i.e. cost of coal is about $ 120. As can be seen from the above, coal and biomass particles are the most economical. Wherein the combustion of coal is difficult to control, and the actual consumption costs considerably biomass particles. However, polluting coal boiler is very large, and the biomass boiler is both economical, and environmentally friendly. Accordingly, we can see that biomass pellet boiler is the best future direction of development of the industry boiler, the boiler will also become the industry mainstream.
Combustion conditions provides rapid and substantially complete combustion of 1, a relatively high furnace temperature: the chemical reaction is the basic condition of combustion, fuel ignition and stable combustion, burn have a significant impact, maintaining a suitably high temperature furnace to important. Of course, when the furnace temperature is too high, consider the problem of slagging 1ton industrial fired boilers. 2, the air supply amount: the amount of air supply, is to provide enough oxygen for the fuel, which is the original conditions of the combustion reaction. Air supply, fuel not get enough oxygen, it can not achieve complete combustion. But excessive air, the furnace temperature will lead to loss and exhaust loss increases. 3, good mixing conditions: Mixing is an important physical conditions of the combustion reaction. Mixing the hot flue gas in the furnace is heated to reflux of the pulverized coal flow, so as to rapidly fire. Mixing in the furnace is strongly perturbed stream to provide oxygen to the soot combustion stage surface, outward diffusion of carbon dioxide, and to promote post-combustion of the fuel burn, it is an indispensable condition. 4, enough burn time: the fuel in the furnace for a time sufficient to achieve a high degree of fuel burn, which requires a large enough volume of the furnace. Proportional to the volume of the furnace and boiler capacity. Of course, the furnace volume is also characteristics of the fuel combustion, easy to burn fuel, furnace volume can be relatively small. For example, the same capacity of the boiler, furnace volume of fuel than pulverized coal furnace is small, and vanished without burning furnace volume than coal burning bituminous coal furnace volume slightly larger.Free Chat
