steam boiler pressure capacity measuring

What are the precautions when using gas steam boiler pressure capacity measuring? Gas-fired steam boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, it is dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses of life and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", using the boiler should pay attention to the whole of the following:

Recently, Shaanxi Province, to build a good ecological environment, issued a "Blue Sky Battle Shaanxi Province 2019 work program", "clear water Battle of Shaanxi Province 2019 work program", "Shaanxi Province Pure Land Battle 2019 work program", "Shaanxi Castle battle province 2019 work program "and other four major environmental battle to defend the program. Details below.

"Program" is mentioned: this year by optimizing the six policies, tough fight seven games, seven strengthen security measures, the average concentration in urban areas and strive to fine particulate matter (PM2.5) fell 4 percent to ensure that the number of heavy pollution days significantly reduce atmospheric environmental quality improved significantly, people's happiness significantly enhanced blue sky.

3, increase economic policy support to accelerate clean winter heating work, in accordance with the principle of "Jiangyoufalie", the establishment of special funds for air pollution prevention and control arrangements with local ambient air quality to improve performance linkage mechanism.

1, lay the tough restructuring, according to the law closed down quit a number of energy consumption, environmental protection, safety, technology and production of non-compliance or substandard products out of production capacity, before the end of the year, the Guanzhong area basically completed "messy dirty" industrial enterprises and in accordance with regulations cluster comprehensive treatment.

2, tough fight industrial pollution control, focusing on gas-related industrial pollution sources to perform all the installation of flue gas emission standards new online monitoring facilities, the Guanzhong area cement, coke, iron and steel, nonferrous metals, glass, ceramics, tile and other industries, and to ban coal-fired hot air furnace, the coal-fired cogeneration substantially eliminated heating pipe network coverage heating, drying furnace (kiln).

4, clean energy alternatives tough fight, central heating station complete transformation of existing coal-fired clean off the area before the end of the city to clean the heating rate in urban areas off more than 90% before the end of May to complete the Guanzhong area rural village set loose coal governance indeed household inventory; motor vehicle pollution control tough fight, and increase freight railway construction investment, strengthen the construction of urban public transport system, promote high-emission motor vehicle pollution control, Guanzhong area cities and built-up area buses in the proportion of new energy vehicles to achieve 80 %, starting July 1, the province's implementation of six national emissions standards.

"Program" also pointed out that by strengthening the organizational leadership, strengthen environmental law enforcement, special inspectors carry out inspections of air pollution, strengthen grid environment supervision, improve environmental monitoring and control network, strengthen science and technology infrastructure support, strict accountability assessment 7 safeguards to ensure that work effectively.

szs water tube boiler induced draft fan needs it? For now the commonly used boiler needs to be equipped with the induced draft fan according to the scene. Further, depending on the type of fuel, the proportion of the air required for combustion is slightly larger. For example, an air ratio of gas per cubic meter of gas demand 1:10 10 m3 air, one ton boiler 700 kilowatts and 66 cubic meters of gas required for combustion air 660 m3. In ensuring the pressure in the boiler furnace micro auxiliary premise than 660 cubic meters per hour can be configured induced draft fan. szs water tube boiler induced draft fan needs it? At the same time, it has estimated air volume and tonnage of the boiler boiler directly related to the amount of smoke that is directly related to: the estimated amount of gas stratified combustion tonnage of each boiler boiler of 1250 cubic meters per hour, when air leakage coefficient of 1.55, when the exhaust gas temperature is 200 degrees, the flue gas volume of about 2500 m3 / hr. Conventional supporting the motor power as follows: One ton of 5.5 kilowatts, 1.1 kilowatts draft fan boiler blower to blower 11KW 2 t, t to blower fan 3KW4 22kW, 37kW inducer blower 5.5kW6T boiler, boiler fan blower 7.5KW10 tons 45kW, fans 15kW20 tons 90 kW boiler induced draft fan blower 55kw

How module boiler blowdown 1) opening the valve inside the sewage; (2) open the valve slowly outward discharge of sewage to be warmed and sewage pipes; (3) on and off several times from the outer sewage valve, slowly red wash liquid in the boiler fouling, so that the liquid discharge best dirt; (4) turn off the valve inside the sewage, between these two discharge of sewage water in the valve drained; (5) turn off the valve outside the sewage, the sewage termination.
