coal-fired steam hot water boiler made in china

Main contents of boiler energy efficiency test:

1. Boiler thermal efficiency test: a) determination of boiler evaporation; b) boiler excess air coefficient detection; c) exhaust smoke temperature detection; d) fuel combustion efficiency test; e) boiler thermal efficiency test; f) fuel consumption; g) Steam to coal ratio.

2. Boiler new product stereotyped energy efficiency test: Determine whether the boiler thermal performance indicators are consistent with the design and determine the operation mode of the equipment. Such as boiler evaporation, boiler thermal efficiency, combustion efficiency, various heat losses and so on.

3. Boiler operation adjustment test: Determine the most economical operation mode of the boiler and identify defects in the boiler operation. Such as boiler maximum load, boiler minimum load, fuel requirements, economic load, reasonable exhaust gas temperature, optimum wind coal ratio, excess air ratio, secondary air ratio and so on.

4. Comparative test of thermal performance before and after boiler reform: changes in evaporation, effects of combustion, thermal efficiency of boilers, etc.

5, fuel industry analysis, elemental analysis: to judge the quality of oil, gas and other fuels, easy for enterprises to control the quality of fuel into the plant.

6, water quality testing, scale analysis: determine the quality of water, control the boiler water indicators to prevent boiler fouling.

Some of the causes direct impact on the thermal efficiency of horizontal steam boiler of the country are carrying out a blaze of glory roaring coal to natural gas operations, the choice of horizontal steam boiler, greatly reducing the fine dust contaminated with dust, along with toxic gases such as nitrogen oxides emissions It has also been suppressed. Thermal efficiency is a key measure of horizontal steam boiler, a good start and that is that let you look at some of the causes direct impact on the thermal efficiency of horizontal steam boiler. Through research departments, the heat loss of horizontal steam boiler is very important from two aspects: the combustion air-fuel ratio is not satisfactory and Smoke and heat loss. Smoke and heat loss reduction should be modified in the tail horizontal steam boiler soot waste heat recycling install, or choose would be more leading series condensing boilers. Combustion air-fuel ratio over the substandard Analysis: common horizontal ejector-type steam boiler burner choice, without the formation of air-fuel ratio can be flexibly adjusted. Most of the horizontal steam boiler selected non-automatic strong emission burner, leading to the root causes of unsatisfactory air-fuel ratio has the following areas: air-fuel ratio is not ideal is more important is divided into two kinds of probability: When an excess of oxygen, there will be endless excessive cold air is heat conduction, resulting in increased energy consumption horizontal steam boilers, hot horizontal steam boiler efficiency decreased; when oxygen is not standard, incomplete combustion occurs, generating heat horizontal steam boiler efficiency decreased.

Boiler startup startup boiler combustion adjustment method should pay attention to the flame monitoring, combustion and make adjustments as follows: (1) correct the ignition. Adequate ventilation furnace before ignition, the ignition first investment ignition device (or torch), then turn the gun. (2) diagonally administered fire mouth, pay attention to timely switch, the flash point was observed nozzle suitable fire, flame sought uniformly distributed in the furnace. (3) to adjust the lead note, air volume, furnace pressure should not be too large. (4) in particular to monitor exhaust gas temperature when combustion instability, the occurrence of the back pass to prevent the secondary combustion. (5) to maximize the temperature of primary air, secondary air is fed reasonable depending on the fuel. Adjusting the temperature difference between both sides of the cigarette. Do pulverizing system-OFF stable (6) operation. Stoker coal under stable powder machine speed and stability. Coal with wind stability and oxygen stable. Steam temperature, steam pressure increase stability and load stability liter.

Jinzhou construction and installation company needs an electric heating coal-fired steam hot water boiler made in china house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.
