A: Operating pressure (also called operating pressure) refers to the pressure at the top of the vessel during normal process operations. The maximum working pressure refers to the highest pressure that may occur during normal process operations. When the pressure exceeds this value, the safety device on the container will act. The determination of the maximum working pressure and the design pressure of the working medium refer to the pressure used to determine the calculated wall thickness of the container and its component dimensions at the corresponding design temperature. The "Supervision Regulations for Pressure Vessel Safety Technology" stipulates that the design pressure of the vessel must not be lower than the maximum working pressure. Pressure vessels equipped with safety relief devices shall not be designed to have a pressure lower than the opening pressure or burst pressure of the safety relief device. The working temperature of the pressure vessel refers to the temperature of the working medium inside the vessel during normal operation, that is, the temperature of the medium. The design temperature refers to the highest or lowest temperature that the shell wall or element metal may reach under the corresponding design pressure during normal operation of the vessel. When the temperature of the shell wall or element metal is below -20°C, the design temperature is determined by the lowest temperature. In addition, the design temperature is always selected according to the maximum temperature. The operating temperature of the pressure vessel refers to the temperature of the medium, and the design temperature refers to the design temperature of the housing.

64. Toxic effects of common chemical substances:
Chlorine (Cl2): Yellow-green gas, soluble in water, alkali solution, carbon disulfide and carbon tetrachloride. With carbon monoxide can generate more toxic phosgene. Chlorine dissolves in water to produce hydrochloric acid and hypochlorous acid, producing local irritation. It mainly damages the upper respiratory tract and bronchial mucosa, causing bronchospasm, bronchitis and peribronchitis, and severe pulmonary edema. After inhalation of high concentrations of chlorine, vagal reflexive heartbeats were arrested and died of "electrical shock".
65. Sulphur dioxide (SO2): colorless gas, 2.3 times the density of air. Pressure can be liquefied, the liquid relative density 1.434, boiling point -10 °C. Soluble in water, ethanol and ether. After inhalation of the respiratory tract, sulfite and sulfuric acid are generated on the wet surface of the mucous membrane, producing a strong stimulatory effect. Massive inhalation can cause laryngeal edema, pulmonary edema, and vocal cord paralysis.
66. Carbon monoxide (CO): colorless, odorless, non-irritating gas. The density is 0.968 times that of air, insoluble in water but soluble in ammonia, ethanol, benzene and acetic acid. The flame is blue when burning. After carbon monoxide is inhaled, it enters the circulation via the alveoli. Carbon monoxide and hemoglobin produce carboxyhemoglobin. Carbon oxygen hemoglobin has no oxygen-carrying capacity and is not easily dissociated, resulting in hypoxia in tissues of the body.
67. Hydrogen cyanide (HCN): A colorless, bitter almond-flavored gas, 0.94 times the density of air, a melting point of -13.4°C, and a boiling point of 26°C. Soluble in water, ethanol and ether. Dissolved in water to produce volatile hydrogen cyanide. Hydrogen cyanide has a strong affinity with trivalent iron ions of oxidized cytochrome oxidase in the body. After firmly binding with it, the enzyme loses its activity, hindering the biological oxidation process, making the tissue cells unable to use oxygen, and causing internal suffocation.
68. Hydrogen Sulfide (H2S): A colorless gas with a rotten egg odor, 1.19 times the density of air and a boiling point of -61.8°C. Soluble in water, ethanol, glycerin, petroleum solvents.
69. The basic method of fire extinguishing:
First, cooling fire extinguishing method:
The fire extinguishing agent is directly injected on the burning object to reduce the burning temperature below the burning point to stop the burning; or the fire extinguishing agent is sprayed on the substance near the fire source so that it will not form a new flame heat radiation effect. Fire point. Cooling fire extinguishing method is a main method of fire extinguishing. Commonly used water and carbon dioxide as fire extinguishing agent cool cooling and extinguishing. The fire extinguishing agent does not participate in the chemical reaction during the fire extinguishing process. This method belongs to the physical fire extinguishing method
Second, the isolation fire extinguishing method:
The unburned combustible material is removed or isolated from the burning material and the supply of combustible material is interrupted so that the combustion stops due to the lack of flammable materials. The specific methods are:
1. Move combustible, flammable, explosive and combustible materials near the fire source;
2. Close the valves of combustible gas and liquid pipes to reduce and prevent combustible substances from entering the combustion zone;
3, trying to block the flammable flammable, combustible liquid;
4. Dismantle flammable buildings adjacent to the fire source to form a space zone to prevent the spread of fire.
Third, suffocation fire suppression law:
Prevent air from flowing into the combustion zone or dilute the air with non-flammable gas, etc., so that the combustion product does not get enough oxygen to extinguish. The specific method is:
1. Cover combustion products with sand, cement, wet sacks, wet cotton quilts, and other nonflammable or flame-retardant materials;
2, spraying spray water, dry powder, foam and other fire extinguishing agent covering the combustion;
3. Infuse containers and equipment that cause fire with inert gases such as steam, nitrogen, or carbon dioxide;
4, closed fire construction, equipment and holes;
5. Spray non-combustible or incombustible liquids (such as carbon dioxide, nitrogen, carbon tetrachloride, etc.) into the combustion area or on the incinerator.

Boiler water quality is not good, it will make the heat surface produce scale, affect the heat transfer effect, waste of fuel. Seriously, it will cause the drum to bulge and the pipe will be blocked and cause an accident. The various impurities contained in the furnace water (including gas, etc.) can also cause corrosion of the metal and shorten the service life of the boiler. Excessive impurities will also affect the quality of the steam, causing the steam to carry water and causing soda to soak. Therefore, strengthening the treatment of boiler water quality is an important part of ensuring boiler safety and economic operation.
