Gas leak occurred boiler gas boiler gas leakage - small steam boiler manufacturers tell you how to do it. Gas boiler leak accident occurred in the use of how to do, let's look at the causes and emergency measures leak accident: 1, gas boiler leaks must be stopped in time, press the emergency stop button is pressed. Second, the main gas valve to close the boiler, cut off the gas supply, then processed according to their specific leakage. 2, the burner leaks: the main valve must be closed immediately boiler, timely reporting to company safety departments, develop detailed contingency plans based on leaks of gas boilers, and find the appropriate technical personnel. 3, indoor gas pipeline leak: shutdown immediate needs, but also turn off the main gas valve boiler room, then promptly told the gas company and its safety and production departments reporting can occur based on a series of gas-fired boiler leak emergency treatment.

The oil industry is one of the key pillar industries. In general, large-scale oil exploration or refining industry, are inseparable from the large steam boiler thermal energy conversion or other use. The reason for selecting steam boilers for processing use, not only because of its high thermal energy, energy saving and environmental protection, but also to meet the demand for petroleum and petrochemical industries. Professional steam boiler in addition to the petrochemical industry can help stabilize the smooth processing use, but also to increase oil production and processing, to help companies generate huge economic benefits. Here follow the small series together to understand the reason the oil industry to use steam boilers.

As a global boiler enterprise, Fangkuai Boiler attaches great importance to the opportunity of communication with customers. Therefore, we have set up a sales team of more than 100 people to visit customer units regularly to check the boiler operation status. Not only can timely search the customer's use feedback and boiler improvement opinions, provide a clearer development direction for equipment research and development, but also assist users in the testing and commissioning of boilers and maintenance work, full life cycle services, and solve customer cooperation projects. The problem is that nobody cares ".

A boiler water testing methods) and storage of water samples taken 1, depending on the volume of water analysis items, only a simple analysis of water samples is generally 500 to 1000 ml. 2, the sample container should be filled with water using a rigid glass or plastic bottle. Never use of wood, paper balls, metal plugs and maize. 3, sampling Note Samples should be slowly into the bottle, it can not produce water rippling. When the water sample into the bottle 10 ml shall be left void, or to prevent the water temperature changes, the cork pushed open. When averaged water sample must be taken at the same time under the same conditions. Determination of the hydrogen ion concentration in water (B) PH value of which depends mainly on the carbon dioxide, bicarbonate ion content of between opposing sulfate ions, but also somewhat affected by other ions. Whichever it is usually expressed negative numbers. Symbol "PH". PH = log [H +] measured PH value method has potential method and colorimetry, only the chapter describes the more common potential method. PH value of measured potential method, the potential difference between the solution is indicated in the measurement and reference electrodes difference generated. The potential of the reference electrode is constant, the potential of the indicator electrode with different PH value of the solution is changed. Thus the electromotive force consisting of a battery can be measured accurately with the compensation method. Using PH PH meter can be directly measured value of the solution. The procedures for measuring PH meter may be used, accuracy of 0.01. (Iii) Determination of calcium measured calcium EDTA volumetric method widely used in the PH> 12 in an alkaline solution, by EDTA titration, acidic chrome blue K- Naphthol Green B as an indicator, titration end point from red to blue 1, a reagent filter paper was immersed in Congo red 0.1% Congo red solution, soaked until removed, and then dried in air, and then cut into 1 × 1 cm pieces of about. Ammonium hydroxide - ammonium chloride buffer solution (pH 10.1) was weighed 67.5 g of ammonium chloride dissolved in 200 ml of water, was added 570 ml of ammonium hydroxide diluted with water to 1000 ml. Weigh calcium standard solution bake for 3 hours at 105 ~ 110 ℃ pure carbon 1.2485 g of calcium beaker, calcium carbonate solution to dissolve just finished boiling rush carbon dioxide with dilute hydrochloric acid. After cooling, into 1000 ml flask, diluted with distilled water to the mark. This solution was 0.5 mg per ml of calcium ions. Tetraacetic acid disodium (EDTA) disodium EDTA weighed 2 g, dissolved in 1000 ml of water to dissolve a little heat, pressing calibration method: lessons per ml standard solution containing 0.5 mg of calcium ions 5 to 10 ml, in a dry 250 ml Erlenmeyer flask, diluted with water to about 50 ml, analysis by calibration procedures; calculated equivalent concentration: where: N - equivalent concentration of calcium standard solution consumed V1-- EDTA titration standard EDTA standard solution few ml solution; the total solution milliliters V - C - 1 ml of the number of milligrams of calcium standard solution of calcium; 20.04-- equivalents of calcium. K-- Acid Chrome Blue mixed indicator naphthol green B; 0.5 g, said acid Chrome Blue K with 1 g of naphthol green B, was dissolved in 5 ml of ammonium hydroxide in PH10.1 - ammonium chloride buffer solution (preparation method see the measurement of magnesium), and add a little hydroxylamine hydrochloride, water was added to 100 ml shake. 2, Procedure Pipette 50 ml of water and 100 samples, 20% sodium hydroxide solution was added 2 to 3 ml, acid chrome blue K-- naphthol green B 2 drops of mixed indicator, titrated with EDTA standard solution changed from red to blue is the end note of the consumption of EDTA standard solution, preservation solution for the determination of magnesium. Calcium content of the sample is calculated as follows: wherein V1-- Titration standard solution consumed few ml EDTA; N - equivalent concentration of EDTA standard solution; V - sample volume, ml. (Iv) the PH10 determination of magnesium in the solution to acid chrome blue K- naphthol green B as indicator titration with EDTA standard solution of calcium, magnesium content. It titration end is blue. Then subtracts the subtraction to yield a calcium content and magnesium content. It may be in solution after titration calcium, magnesium measured continuously adjusted PH value. Assay (e) the sulfate (gravimetric method) with barium sulfate to form sulfuric acid in an acidic solution precipitated barium. Obtained from the sulfate content by weight of barium sulphate (sample when large water content, with hydrochloric acid in advance to be evaporated to dryness, the sulfate measured by the steps below to root damage nitrate: 100 ml water samples taken transparent, injection 250 ml beaker, and 1: 1 solution of 2 ml of hydrochloric acid, heated to boiling, hot slowly added under stirring 10 ml of 5% barium chloride solution, incubated for 2 hours on a water bath or sand bath, or overnight, and then quantitative filter paper with a dense, washed with hot distilled water until free from chloride ions (checking with silver nitrate solution) so far. the precipitate was dried together with the filter paper, into constant weight porcelain crucible, carefully ashing furnace set temperature, calcined at 850 deg.] C to constant weight sulfate ion content of the following formula: sulfate (mg / l) = formula weight of precipitated barium sulfate in W-- (mg); V - measured as the volume of water samples . 1.gb6903-1986 standard boiler water and cooling water measured analysis General 2.gb/t14415-1993 boiler water and cooling water 3.gb/t6908-1986 analysis of the solid matter boiler water and cooling water conductivity analysis Determination 4.gb/t6904.1-1986 pot Determination of mercuric nitrate boiler water and cooling water 6.gb/t14419-1993 Analysis 5.gb/t6905.3-1986 boiler water and cooling water chlorides Analysis Analysis water and cooling water ph glass electrode method of measurement Determination of hardness 8.gb/t6909.2-1986 boiler water and cooling water analysis method for measuring hardness 7.gb/t6909.1-1986 boiler water and cooling water Determination of alkalinity high hardness low hardness 9.gb/ Determination t6913.2-1986 boiler water and cooling water analysis Determination of total inorganic phosphate boiler water and cooling water 10.gb/t6913.4-1993 phosphate phosphate analysis
