The degree of increase in the boiler water temperature per unit time from the ignition of the fire starter in the furnace to the boiling point of water at a temperature of 25°C indicates the cooking starting performance of the coal stove.
3.4 Cooking fire intensity
The heat of boiler water evaporation per unit time during the boiler water evaporation stage indicates the cooking heating capacity of the coal stove. 3.5 Heating fire intensity
The heat absorbed by the jacket water temperature per unit time during the stable heating period indicates the heating capacity of the coal stove. 3.6 Rated heat supply
The specified heating fire intensity of the coal stove.
3.7 Thermal efficiency
The ratio of the sum of the heat absorbed by the boiler water heating and evaporation and the heat absorbed by the water jacket water heating to the heat generated by the fuel put into the furnace indicates the thermal utilization of the coal stove.
3.8 Fire speed after fire blocking

5 Test conditions and preparation
5.1 Test conditions
Ambient temperature: 10-30℃;
Relative humidity: less than 85%;
Wind speed: less than 1.0m/s;
The test coal furnace is far away from other heat sources. When multiple furnaces are tested at the same location, the distance between them is greater than 1m. d.
5.2 Test preparation
5.2.1 Calibrate the instrument to the specified requirements.
Evaporation pot diameter
GB/T 16155—1996
5.2.2 Determine the low calorific value of naturally air-dried kindling, ignition coal and coal in accordance with GB213 and GB5186. 5.2.3 Install thermometers at the water inlet and outlet pipes of the water jacket. The distance between the thermometer and the furnace body should be less than three times the water pipe diameter. 5.2.4 According to the rated heat supply of the coal furnace, determine the test coal quantity Gm, the initial boiler water volume Gc, and the size of the evaporation pot (see Table 1). The coal quantity should ensure the rated heat supply of about 4 hours. For the initial boiler water volume Gc and the size of the evaporation pot of the multi-hole coal furnace, it is determined according to the rated heat supply of a single hole. 5.2.5 Weigh and record the coal (Gm), the amount of ignition coal (Gm) and the amount of ignition match (Gm2). 5.2.6 Insert the thermometer into the pot through the center hole of the pot cover, and use the thermometer bracket to make the temperature sensing point about 10mm away from the bottom of the pot. 6 Test procedure
6.1 Fill the water jacket with water in the water tank and record the water inlet temperature ti. 6.2 Fill the evaporator with the initial amount of water (Gc) at a temperature of 25C and cover the pot. 6.3 Ignite and record the ignition time T1 of the ignition material, put the evaporator on and start the test. 6.4 When the water temperature of the water jacket rises to 75℃, open the switch valve to drain water into the water bucket. At the same time, observe the change of the outlet water temperature, adjust the flow limiting valve, and control the outlet water temperature at 75~80℃. When the outlet water temperature is lower than 75℃, close the switch valve to stop draining water. During the draining period, record the outlet water temperature every 2 minutes, and measure the outlet water volume and average outlet water temperature. Repeat this process. 6.5 During the heating test, record the inlet water temperature every 10 minutes. 6.6 When the water temperature rises to the boiling point, open the pot cover and record the time T and the water temperature, and start the cooking fire intensity test. 6.7 During the evaporation of the water, record the water temperature every 5 minutes and calculate the average temperature value. After the water evaporates for 1 hour, cover the pot cover and immediately weigh the remaining water volume Gca to end the cooking fire intensity test. 6.8 Adjust the coal stove and pots to the stable heating state, and start the 90-minute heating fire intensity test according to the processes of 6.4 and 6.5 (no adjustment is allowed after 10 minutes of the test). Calculate the total water output Gn2, the average water output temperature tn2 and the average inlet water temperature ti2 in this stage, and end the heating fire intensity test.
6.9 Repeat the process of 6.4 and 6.5. When the jacket water temperature cannot rise to 75℃ within 10 minutes, end the heating part test. Calculate the total water output Gns, average water output temperature tn3 and average water inlet temperature ti3 of the whole process. 6.10 Measure the water capacity Gn and temperature tn of the jacket water at the end of the heating test. 6.11 For coal stoves with blowers, the power consumption E must be recorded. 6.12 Fire sealing performance test
6.12.1 Adjust the coal stove to enter the fire sealing state. 6.12.2 After the fire is sealed for 10 hours, the coal stove is adjusted. It is allowed to add coal, but it is not allowed to add kindling matches or kindling coal. 6.12.3 For household water heating coal stoves, place the evaporator with the initial water volume (Gc1) and water temperature of 25℃, and record this moment T3. 6.12.4 When the water temperature rises to the boiling point, record this moment T and the water temperature tcz, and the fire sealing performance test is terminated. During the fire sealing performance test, the heating part is carried out according to the process of 6.4.
6.12.5 For household water heating coal stoves, the fire sealing performance test is terminated after the rated heating capacity is reached. 6.13 Determination of carbon monoxide concentration in flue gas
6.13.1 According to GB6412, use a flue gas sampler to extract smoke samples every 30 minutes from the straight section of the smoke window (the straight section before the hole is not less than three times the diameter of the smoke window, and the straight section after the hole is not less than two times the diameter of the smoke window) during the cooking fire intensity and heating fire intensity test, and the total number of extractions shall not be less than three times.
6.13.2 Use a long-type carbon monoxide rapid test tube to determine the concentration of carbon monoxide each time. 6.14 Extinguish the open flame, tidy up the site, and after the furnace temperature cools to the ambient temperature, repeat the test once according to the above method. 7 Calculation and evaluation of test results
