To ensure the safety of special equipment such as fire tube boiler feed water qualitys, in normal use, to further promote the comprehensive management of environmental pollution, since April this year, Khorgas Market Supervision Administration of Quality Supervision Bureau for the joint Yili area within the jurisdiction of Khorgas , launched a special safety inspection activities boilers.
Law enforcement officers to be included within the jurisdiction of the major hazard of 12 boiler units of a total of 21 boilers individually conduct a special inspection, focus on examination of the "three implementation, two certified, a test, a plan," the implementation of a detailed view of boiler safety management system, run records.
Test results showed that most of the boiler unit security management more standardized, but there are still some units use boilers run records were incomplete, part of the boiler has to inspection cycle, has been scrapped or dismantled boiler is not write-off and other issues, law enforcement officers to issue on-site boiler sealed, and ordered boiler unit for rectification.
Description of the main steam pressure fire tube boiler feed water quality and boiler auxiliary equipment related to what is: the main steam pressure in the boiler, the relevant factors, there is what? For the new boiler, which prior to use, what needs work? As well as different types of boilers, auxiliary boilers on whether the same? These issues will be raised, its main purpose is to solve, so below, without further ado, to proceed immediately to save time and improve everyone's learning efficiency. 1. The main steam pressure boiler, and its related factors? Main steam pressure in the boiler, associated factors, and if, to generalize summary, then, there are mainly the following, are as follows: Factor 1: combustion boiler, which is enhanced or diminished. Factors II: specific changes in the heat transfer in the boiler, is has been enhanced or weakened. Three factors: the boiler heating surface, leaks and other issues, such as which waterwall leak or superheater. Four factors: the boiler feed water temperature has changed, or the burning flame height changes. Five factors: the boiler safety doors and pressure relief valve action, whether there will be corresponding changes or abnormalities.
10 tons of gas hot water fire tube boiler feed water quality depreciation calculation depreciation is due to the gradual loss of fixed assets transferred in the course of the merchandise or the cost of that part of the value to go, but also business due to the use of fixed assets used in its production process assessed useful life of fixed assets cost money. 10 tons of gas hot water boilers are industrial boiler, equipment belonging to the class. In accordance with the Enterprise Income Tax Law, depreciation of fixed assets a minimum period of 10 years, residual rate set at 5% or 10%. If the 10 tons / hr of a gas hot water boiler for heating use, should process equipment, mutatis mutandis, the age of 10 years. In calculating the depreciation of fixed assets, in addition to foreign-funded enterprises to deduct the residual value according to the proportion of 5%. Assuming that the cost of 10 t / h of gas hot water boiler purchase of 500,000, the annual depreciation amount of the boiler: 500000- (500,000 * 5%) / 10 = 497,500 yuan. Suppose residual rate set at 5%, is expected to use for 10 years, the 10 tons / hour of industrial gas boiler depreciation rate = (1-5%) / 10 * 100% = 9.5% of the 10 t / h of gas hot water boiler monthly depreciation rate = 9.5% ÷ 12 = 0.79%. The monthly depreciation 10 tons / hour gas hot water boiler = 0.79% * 500,000 = 3950 yuan. In recent years, as an environmentally friendly gas-fired boiler to get the type of boiler widely welcomed by all walks of life, whether it is the depreciation rate for the gas boiler, the initial investment, annual operating costs and environmental aspects of government policy, gas boiler has played a great advantage.

High pressure steam fire tube boiler feed water qualitys which use failure and solutions? Belongs to a high pressure steam boiler energy conversion device, by a certain energy input thereto and further plurality of organic heat output of steam, hot water having a certain temperature and the like. High pressure steam boiler beautiful because of stable structure, stable and rational water system advantages are widely used in many industries, such as life energy in a steady stream of hot water supply, or a train station, shipbuilding and other industries in the conversion equipment. Even good quality formal high-pressure steam boiler due to many different reasons and various failures during operation of the Central Standing Committee thereby affecting work efficiency, let's take a look at the high-pressure steam boiler may malfunction and corresponding reason appear in the course and solutions.
